+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+## Development status
+
+**ℹ️ Consider go-toml v2!**
+
+The next version of go-toml is in [active development][v2-dev], and
+[nearing completion][v2-map].
+
+Though technically in beta, v2 is already more tested, [fixes bugs][v1-bugs],
+and [much faster][v2-bench]. If you only need reading and writing TOML documents
+(majority of cases), those features are implemented and the API unlikely to
+change.
+
+The remaining features (Document structure editing and tooling) will be added
+shortly. While pull-requests are welcome on v1, no active development is
+expected on it. When v2.0.0 is released, v1 will be deprecated.

-
-```
-  ▾ appName/
-    ▾ cmd/
-        add.go
-        your.go
-        commands.go
-        here.go
-      main.go
-```
-
-In a Cobra app, typically the main.go file is very bare. It serves one purpose: initializing Cobra.
-

-package main
-
-import (
-  "{pathToYourApp}/cmd"

-func main() {
-  cmd.Execute()
-}
-```
-
-## Using the Cobra Generator
-
-Cobra provides its own program that will create your application and add any
-commands you want. It's the easiest way to incorporate Cobra into your application.
-
-[Here](https://github.com/spf13/cobra/blob/master/cobra/README.md) you can find more information about it.
-
-## Using the Cobra Library
-
-To manually implement Cobra you need to create a bare main.go file and a rootCmd file.
-You will optionally provide additional commands as you see fit.
-
-### Create rootCmd
-
-Cobra doesn't require any special constructors. Simply create your commands.
-
-Ideally you place this in app/cmd/root.go:
-
-```go
-var rootCmd = &cobra.Command{
-  Use:   "hugo",
-  Short: "Hugo is a very fast static site generator",
-  Long: `A Fast and Flexible Static Site Generator built with
-                love by spf13 and friends in Go.
-                Complete documentation is available at http://hugo.spf13.com`,
-  Run: func(cmd *cobra.Command, args []string) {
-    // Do Stuff Here
-  },
-}
-
-func Execute() {
-  if err := rootCmd.Execute(); err != nil {
-    fmt.Fprintln(os.Stderr, err)
-    os.Exit(1)
-  }
-}
-```
-
-You will additionally define flags and handle configuration in your init() function.
-
-For example cmd/root.go:
-
-```go
-package cmd
-
-import (
-	"fmt"
-	"os"
-
-	homedir "github.com/mitchellh/go-homedir"
-	"github.com/spf13/cobra"
-	"github.com/spf13/viper"
-)
-
-var (
-	// Used for flags.
-	cfgFile     string
-	userLicense string
-
-	rootCmd = &cobra.Command{
-		Use:   "cobra",
-		Short: "A generator for Cobra based Applications",
-		Long: `Cobra is a CLI library for Go that empowers applications.
-This application is a tool to generate the needed files
-to quickly create a Cobra application.`,
-	}
-)
-
-// Execute executes the root command.
-func Execute() error {
-	return rootCmd.Execute()
-}
-
-func init() {
-	cobra.OnInitialize(initConfig)
-
-	rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)")
-	rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "author name for copyright attribution")
-	rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "name of license for the project")
-	rootCmd.PersistentFlags().Bool("viper", true, "use Viper for configuration")
-	viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
-	viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper"))
-	viper.SetDefault("author", "NAME HERE <EMAIL ADDRESS>")
-	viper.SetDefault("license", "apache")
-
-	rootCmd.AddCommand(addCmd)
-	rootCmd.AddCommand(initCmd)
-}
-
-func initConfig() {
-	if cfgFile != "" {
-		// Use config file from the flag.
-		viper.SetConfigFile(cfgFile)
-	} else {
-		// Find home directory.
-		home, err := homedir.Dir()
-		cobra.CheckErr(err)
-
-		// Search config in home directory with name ".cobra" (without extension).
-		viper.AddConfigPath(home)
-		viper.SetConfigName(".cobra")
-	}
-
-	viper.AutomaticEnv()
-
-	if err := viper.ReadInConfig(); err == nil {
-		fmt.Println("Using config file:", viper.ConfigFileUsed())
-	}
-}
-```
-
-### Create your main.go
-
-With the root command you need to have your main function execute it.
-Execute should be run on the root for clarity, though it can be called on any command.
-
-In a Cobra app, typically the main.go file is very bare. It serves one purpose: to initialize Cobra.
-
-```go
-package main
-
-import (
-  "{pathToYourApp}/cmd"
-)
-
-func main() {
-  cmd.Execute()
-}
-```
-
-### Create additional commands
-
-Additional commands can be defined and typically are each given their own file
-inside of the cmd/ directory.
-
-If you wanted to create a version command you would create cmd/version.go and
-populate it with the following:
-
-```go
-package cmd
-
-import (
-  "fmt"
-
-  "github.com/spf13/cobra"
-)
-
-func init() {
-  rootCmd.AddCommand(versionCmd)
-}
-
-var versionCmd = &cobra.Command{
-  Use:   "version",
-  Short: "Print the version number of Hugo",
-  Long:  `All software has versions. This is Hugo's`,
-  Run: func(cmd *cobra.Command, args []string) {
-    fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
-  },
-}
-```
-
-### Returning and handling errors
-
-If you wish to return an error to the caller of a command, `RunE` can be used.
-
-```go
-package cmd
-
-import (
-  "fmt"
-
-  "github.com/spf13/cobra"
-)
-
-func init() {
-  rootCmd.AddCommand(tryCmd)
-}
-
-var tryCmd = &cobra.Command{
-  Use:   "try",
-  Short: "Try and possibly fail at something",
-  RunE: func(cmd *cobra.Command, args []string) error {
-    if err := someFunc(); err != nil {
-	return err
-    }
-    return nil
-  },
-}
-```
-
-The error can then be caught at the execute function call.
-
-## Working with Flags
-
-Flags provide modifiers to control how the action command operates.
-
-### Assign flags to a command
-
-Since the flags are defined and used in different locations, we need to
-define a variable outside with the correct scope to assign the flag to
-work with.
-
-```go
-var Verbose bool
-var Source string
-```
-
-There are two different approaches to assign a flag.
-
-### Persistent Flags
-
-A flag can be 'persistent', meaning that this flag will be available to the
-command it's assigned to as well as every command under that command. For
-global flags, assign a flag as a persistent flag on the root.
-
-```go
-rootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output")
-```
-
-### Local Flags
-
-A flag can also be assigned locally, which will only apply to that specific command.
-
-```go
-localCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from")
-```
-
-### Local Flag on Parent Commands
-
-By default, Cobra only parses local flags on the target command, and any local flags on
-parent commands are ignored. By enabling `Command.TraverseChildren`, Cobra will
-parse local flags on each command before executing the target command.
-
-```go
-command := cobra.Command{
-  Use: "print [OPTIONS] [COMMANDS]",
-  TraverseChildren: true,
-}
-```
-
-### Bind Flags with Config
-
-You can also bind your flags with [viper](https://github.com/spf13/viper):
-```go
-var author string
-
-func init() {
-  rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution")
-  viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
-}
-```
-
-In this example, the persistent flag `author` is bound with `viper`.
-**Note**: the variable `author` will not be set to the value from config,
-when the `--author` flag is not provided by user.
-
-More in [viper documentation](https://github.com/spf13/viper#working-with-flags).
-
-### Required flags
-
-Flags are optional by default. If instead you wish your command to report an error
-when a flag has not been set, mark it as required:
-```go
-rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
-rootCmd.MarkFlagRequired("region")
-```
-
-Or, for persistent flags:
-```go
-rootCmd.PersistentFlags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
-rootCmd.MarkPersistentFlagRequired("region")
-```
-
-## Positional and Custom Arguments
-
-Validation of positional arguments can be specified using the `Args` field
-of `Command`.
-
-The following validators are built in:
-
-- `NoArgs` - the command will report an error if there are any positional args.
-- `ArbitraryArgs` - the command will accept any args.
-- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`.
-- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args.
-- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args.
-- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args.
-- `ExactValidArgs(int)` - the command will report an error if there are not exactly N positional args OR if there are any positional args that are not in the `ValidArgs` field of `Command`
-- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args.
-
-An example of setting the custom validator:
-
-```go
-var cmd = &cobra.Command{
-  Short: "hello",
-  Args: func(cmd *cobra.Command, args []string) error {
-    if len(args) < 1 {
-      return errors.New("requires a color argument")
-    }
-    if myapp.IsValidColor(args[0]) {
-      return nil
-    }
-    return fmt.Errorf("invalid color specified: %s", args[0])
-  },
-  Run: func(cmd *cobra.Command, args []string) {
-    fmt.Println("Hello, World!")
-  },
-}
-```
-
-## Example
-
-In the example below, we have defined three commands. Two are at the top level
-and one (cmdTimes) is a child of one of the top commands. In this case the root
-is not executable, meaning that a subcommand is required. This is accomplished
-by not providing a 'Run' for the 'rootCmd'.
-
-We have only defined one flag for a single command.
-
-More documentation about flags is available at https://github.com/spf13/pflag

-package main
-

-  "fmt"

-## Help Command
-
-Cobra automatically adds a help command to your application when you have subcommands.
-This will be called when a user runs 'app help'. Additionally, help will also
-support all other commands as input. Say, for instance, you have a command called
-'create' without any additional configuration; Cobra will work when 'app help
-create' is called.  Every command will automatically have the '--help' flag added.
-
-### Example
-
-The following output is automatically generated by Cobra. Nothing beyond the
-command and flag definitions are needed.
-
-    $ cobra help
-
-    Cobra is a CLI library for Go that empowers applications.
-    This application is a tool to generate the needed files
-    to quickly create a Cobra application.
-
-    Usage:
-      cobra [command]
-
-    Available Commands:
-      add         Add a command to a Cobra Application
-      help        Help about any command
-      init        Initialize a Cobra Application
-
-    Flags:
-      -a, --author string    author name for copyright attribution (default "YOUR NAME")
-          --config string    config file (default is $HOME/.cobra.yaml)
-      -h, --help             help for cobra
-      -l, --license string   name of license for the project
-          --viper            use Viper for configuration (default true)
-
-    Use "cobra [command] --help" for more information about a command.
-
-
-Help is just a command like any other. There is no special logic or behavior
-around it. In fact, you can provide your own if you want.
-
-### Defining your own help
-
-You can provide your own Help command or your own template for the default command to use
-with following functions:
-
-```go
-cmd.SetHelpCommand(cmd *Command)
-cmd.SetHelpFunc(f func(*Command, []string))
-cmd.SetHelpTemplate(s string)
-```
-
-The latter two will also apply to any children commands.
-
-## Usage Message
-
-When the user provides an invalid flag or invalid command, Cobra responds by
-showing the user the 'usage'.
-
-### Example
-You may recognize this from the help above. That's because the default help
-embeds the usage as part of its output.
-
-    $ cobra --invalid
-    Error: unknown flag: --invalid
-    Usage:
-      cobra [command]
-
-    Available Commands:
-      add         Add a command to a Cobra Application
-      help        Help about any command
-      init        Initialize a Cobra Application
-
-    Flags:
-      -a, --author string    author name for copyright attribution (default "YOUR NAME")
-          --config string    config file (default is $HOME/.cobra.yaml)
-      -h, --help             help for cobra
-      -l, --license string   name of license for the project
-          --viper            use Viper for configuration (default true)
-
-    Use "cobra [command] --help" for more information about a command.
-
-### Defining your own usage
-You can provide your own usage function or template for Cobra to use.
-Like help, the function and template are overridable through public methods:
-
-```go
-cmd.SetUsageFunc(f func(*Command) error)
-cmd.SetUsageTemplate(s string)
-```
-
-## Version Flag
-
-Cobra adds a top-level '--version' flag if the Version field is set on the root command.
-Running an application with the '--version' flag will print the version to stdout using
-the version template. The template can be customized using the
-`cmd.SetVersionTemplate(s string)` function.
-
-## PreRun and PostRun Hooks
-
-It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`.  The `Persistent*Run` functions will be inherited by children if they do not declare their own.  These functions are run in the following order:
-
-- `PersistentPreRun`
-- `PreRun`
-- `Run`
-- `PostRun`
-- `PersistentPostRun`
-
-An example of two commands which use all of these features is below.  When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`:
-
-```go
-package main
-
-import (
-  "fmt"
-
-  "github.com/spf13/cobra"
-)
-
-func main() {
-
-  var rootCmd = &cobra.Command{
-    Use:   "root [sub]",
-    Short: "My root command",
-    PersistentPreRun: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args)
-    },
-    PreRun: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside rootCmd PreRun with args: %v\n", args)
-    },
-    Run: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside rootCmd Run with args: %v\n", args)
-    },
-    PostRun: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside rootCmd PostRun with args: %v\n", args)
-    },
-    PersistentPostRun: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args)
-    },
-  }
-
-  var subCmd = &cobra.Command{
-    Use:   "sub [no options!]",
-    Short: "My subcommand",
-    PreRun: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside subCmd PreRun with args: %v\n", args)
-    },
-    Run: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside subCmd Run with args: %v\n", args)
-    },
-    PostRun: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside subCmd PostRun with args: %v\n", args)
-    },
-    PersistentPostRun: func(cmd *cobra.Command, args []string) {
-      fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args)
-    },
-  }
-
-  rootCmd.AddCommand(subCmd)
-
-  rootCmd.SetArgs([]string{""})
-  rootCmd.Execute()
-  fmt.Println()
-  rootCmd.SetArgs([]string{"sub", "arg1", "arg2"})
-  rootCmd.Execute()
-}
-```
-
-Output:
-```
-Inside rootCmd PersistentPreRun with args: []
-Inside rootCmd PreRun with args: []
-Inside rootCmd Run with args: []
-Inside rootCmd PostRun with args: []
-Inside rootCmd PersistentPostRun with args: []
-
-Inside rootCmd PersistentPreRun with args: [arg1 arg2]
-Inside subCmd PreRun with args: [arg1 arg2]
-Inside subCmd Run with args: [arg1 arg2]
-Inside subCmd PostRun with args: [arg1 arg2]
-Inside subCmd PersistentPostRun with args: [arg1 arg2]
-```
-
-## Suggestions when "unknown command" happens
-
-Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
-
-```
-$ hugo srever
-Error: unknown command "srever" for "hugo"
-
-Did you mean this?
-        server
-
-Run 'hugo --help' for usage.
-```
-
-Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion.
-
-If you need to disable suggestions or tweak the string distance in your command, use:
-
-```go
-command.DisableSuggestions = true
-```
-
-or
-
-```go
-command.SuggestionsMinimumDistance = 1
-```
-
-You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example:
-
-```
-$ kubectl remove
-Error: unknown command "remove" for "kubectl"
-
-Did you mean this?
-        delete
-
-Run 'kubectl help' for usage.
-```
-
-## Generating documentation for your command
-
-Cobra can generate documentation based on subcommands, flags, etc. Read more about it in the [docs generation documentation](doc/README.md).
-
-## Generating shell completions
-
-Cobra can generate a shell-completion file for the following shells: bash, zsh, fish, PowerShell. If you add more information to your commands, these completions can be amazingly powerful and flexible.  Read more about it in [Shell Completions](shell_completions.md).

 For backward compatibility, Cobra still supports its legacy dynamic completion solution (described below).  Unlike the `ValidArgsFunction` solution, the legacy solution will only work for Bash shell-completion and not for other shells. This legacy solution can be used along-side `ValidArgsFunction` and `RegisterFlagCompletionFunc()`, as long as both solutions are not used for the same command.  This provides a path to gradually migrate from the legacy solution to the new solution.
 
+**Note**: Cobra's default `completion` command uses bash completion V2.  If you are currently using Cobra's legacy dynamic completion solution, you should not use the default `completion` command but continue using your own.
+
 The legacy solution allows you to inject bash functions into the bash completion script.  Those bash functions are responsible for providing the completion choices for your own completions.

 For backward compatibility, Cobra still supports its bash legacy dynamic completion solution.
 Please refer to [Bash Completions](bash_completions.md) for details.
 
+### Bash completion V2
+
+Cobra provides two versions for bash completion.  The original bash completion (which started it all!) can be used by calling
+`GenBashCompletion()` or `GenBashCompletionFile()`.
+
+A new V2 bash completion version is also available.  This version can be used by calling `GenBashCompletionV2()` or
+`GenBashCompletionFileV2()`.  The V2 version does **not** support the legacy dynamic completion
+(see [Bash Completions](bash_completions.md)) but instead works only with the Go dynamic completion
+solution described in this document.
+Unless your program already uses the legacy dynamic completion solution, it is recommended that you use the bash
+completion V2 solution which provides the following extra features:
+- Supports completion descriptions (like the other shells)
+- Small completion script of less than 300 lines (v1 generates scripts of thousands of lines; `kubectl` for example has a bash v1 completion script of over 13K lines)
+- Streamlined user experience thanks to a completion behavior aligned with the other shells 
+
+`Bash` completion V2 supports descriptions for completions. When calling `GenBashCompletionV2()` or `GenBashCompletionFileV2()`
+you must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra
+will provide the description automatically based on usage information.  You can choose to make this option configurable by
+your users.
+
+```
+# With descriptions
+$ helm s[tab][tab]
+search  (search for a keyword in charts)           status  (display the status of the named release)
+show    (show information of a chart)
+
+# Without descriptions
+$ helm s[tab][tab]
+search  show  status
+```
+**Note**: Cobra's default `completion` command uses bash completion V2.  If for some reason you need to use bash completion V1, you will need to implement your own `completion` command. 
 ## Zsh completions
 
 Cobra supports native zsh completion generated from the root `cobra.Command`.

+# User Guide
+
+While you are welcome to provide your own organization, typically a Cobra-based
+application will follow the following organizational structure:
+
+```
+  ▾ appName/
+    ▾ cmd/
+        add.go
+        your.go
+        commands.go
+        here.go
+      main.go
+```
+
+In a Cobra app, typically the main.go file is very bare. It serves one purpose: initializing Cobra.
+
+```go
+package main
+
+import (
+  "{pathToYourApp}/cmd"
+)
+
+func main() {
+  cmd.Execute()
+}
+```
+
+## Using the Cobra Generator
+
+Cobra provides its own program that will create your application and add any
+commands you want. It's the easiest way to incorporate Cobra into your application.
+
+[Here](https://github.com/spf13/cobra/blob/master/cobra/README.md) you can find more information about it.
+
+## Using the Cobra Library
+
+To manually implement Cobra you need to create a bare main.go file and a rootCmd file.
+You will optionally provide additional commands as you see fit.
+
+### Create rootCmd
+
+Cobra doesn't require any special constructors. Simply create your commands.
+
+Ideally you place this in app/cmd/root.go:
+
+```go
+var rootCmd = &cobra.Command{
+  Use:   "hugo",
+  Short: "Hugo is a very fast static site generator",
+  Long: `A Fast and Flexible Static Site Generator built with
+                love by spf13 and friends in Go.
+                Complete documentation is available at http://hugo.spf13.com`,
+  Run: func(cmd *cobra.Command, args []string) {
+    // Do Stuff Here
+  },
+}
+
+func Execute() {
+  if err := rootCmd.Execute(); err != nil {
+    fmt.Fprintln(os.Stderr, err)
+    os.Exit(1)
+  }
+}
+```
+
+You will additionally define flags and handle configuration in your init() function.
+
+For example cmd/root.go:
+
+```go
+package cmd
+
+import (
+	"fmt"
+	"os"
+
+	"github.com/spf13/cobra"
+	"github.com/spf13/viper"
+)
+
+var (
+	// Used for flags.
+	cfgFile     string
+	userLicense string
+
+	rootCmd = &cobra.Command{
+		Use:   "cobra",
+		Short: "A generator for Cobra based Applications",
+		Long: `Cobra is a CLI library for Go that empowers applications.
+This application is a tool to generate the needed files
+to quickly create a Cobra application.`,
+	}
+)
+
+// Execute executes the root command.
+func Execute() error {
+	return rootCmd.Execute()
+}
+
+func init() {
+	cobra.OnInitialize(initConfig)
+
+	rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)")
+	rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "author name for copyright attribution")
+	rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "name of license for the project")
+	rootCmd.PersistentFlags().Bool("viper", true, "use Viper for configuration")
+	viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
+	viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper"))
+	viper.SetDefault("author", "NAME HERE <EMAIL ADDRESS>")
+	viper.SetDefault("license", "apache")
+
+	rootCmd.AddCommand(addCmd)
+	rootCmd.AddCommand(initCmd)
+}
+
+func initConfig() {
+	if cfgFile != "" {
+		// Use config file from the flag.
+		viper.SetConfigFile(cfgFile)
+	} else {
+		// Find home directory.
+		home, err := os.UserHomeDir()
+		cobra.CheckErr(err)
+
+		// Search config in home directory with name ".cobra" (without extension).
+		viper.AddConfigPath(home)
+		viper.SetConfigType("yaml")
+		viper.SetConfigName(".cobra")
+	}
+
+	viper.AutomaticEnv()
+
+	if err := viper.ReadInConfig(); err == nil {
+		fmt.Println("Using config file:", viper.ConfigFileUsed())
+	}
+}
+```
+
+### Create your main.go
+
+With the root command you need to have your main function execute it.
+Execute should be run on the root for clarity, though it can be called on any command.
+
+In a Cobra app, typically the main.go file is very bare. It serves one purpose: to initialize Cobra.
+
+```go
+package main
+
+import (
+  "{pathToYourApp}/cmd"
+)
+
+func main() {
+  cmd.Execute()
+}
+```
+
+### Create additional commands
+
+Additional commands can be defined and typically are each given their own file
+inside of the cmd/ directory.
+
+If you wanted to create a version command you would create cmd/version.go and
+populate it with the following:
+
+```go
+package cmd
+
+import (
+  "fmt"
+
+  "github.com/spf13/cobra"
+)
+
+func init() {
+  rootCmd.AddCommand(versionCmd)
+}
+
+var versionCmd = &cobra.Command{
+  Use:   "version",
+  Short: "Print the version number of Hugo",
+  Long:  `All software has versions. This is Hugo's`,
+  Run: func(cmd *cobra.Command, args []string) {
+    fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
+  },
+}
+```
+
+### Returning and handling errors
+
+If you wish to return an error to the caller of a command, `RunE` can be used.
+
+```go
+package cmd
+
+import (
+  "fmt"
+
+  "github.com/spf13/cobra"
+)
+
+func init() {
+  rootCmd.AddCommand(tryCmd)
+}
+
+var tryCmd = &cobra.Command{
+  Use:   "try",
+  Short: "Try and possibly fail at something",
+  RunE: func(cmd *cobra.Command, args []string) error {
+    if err := someFunc(); err != nil {
+	return err
+    }
+    return nil
+  },
+}
+```
+
+The error can then be caught at the execute function call.
+
+## Working with Flags
+
+Flags provide modifiers to control how the action command operates.
+
+### Assign flags to a command
+
+Since the flags are defined and used in different locations, we need to
+define a variable outside with the correct scope to assign the flag to
+work with.
+
+```go
+var Verbose bool
+var Source string
+```
+
+There are two different approaches to assign a flag.
+
+### Persistent Flags
+
+A flag can be 'persistent', meaning that this flag will be available to the
+command it's assigned to as well as every command under that command. For
+global flags, assign a flag as a persistent flag on the root.
+
+```go
+rootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output")
+```
+
+### Local Flags
+
+A flag can also be assigned locally, which will only apply to that specific command.
+
+```go
+localCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from")
+```
+
+### Local Flag on Parent Commands
+
+By default, Cobra only parses local flags on the target command, and any local flags on
+parent commands are ignored. By enabling `Command.TraverseChildren`, Cobra will
+parse local flags on each command before executing the target command.
+
+```go
+command := cobra.Command{
+  Use: "print [OPTIONS] [COMMANDS]",
+  TraverseChildren: true,
+}
+```
+
+### Bind Flags with Config
+
+You can also bind your flags with [viper](https://github.com/spf13/viper):
+```go
+var author string
+
+func init() {
+  rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution")
+  viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
+}
+```
+
+In this example, the persistent flag `author` is bound with `viper`.
+**Note**: the variable `author` will not be set to the value from config,
+when the `--author` flag is not provided by user.
+
+More in [viper documentation](https://github.com/spf13/viper#working-with-flags).
+
+### Required flags
+
+Flags are optional by default. If instead you wish your command to report an error
+when a flag has not been set, mark it as required:
+```go
+rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
+rootCmd.MarkFlagRequired("region")
+```
+
+Or, for persistent flags:
+```go
+rootCmd.PersistentFlags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
+rootCmd.MarkPersistentFlagRequired("region")
+```
+
+## Positional and Custom Arguments
+
+Validation of positional arguments can be specified using the `Args` field
+of `Command`.
+
+The following validators are built in:
+
+- `NoArgs` - the command will report an error if there are any positional args.
+- `ArbitraryArgs` - the command will accept any args.
+- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`.
+- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args.
+- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args.
+- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args.
+- `ExactValidArgs(int)` - the command will report an error if there are not exactly N positional args OR if there are any positional args that are not in the `ValidArgs` field of `Command`
+- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args.
+
+An example of setting the custom validator:
+
+```go
+var cmd = &cobra.Command{
+  Short: "hello",
+  Args: func(cmd *cobra.Command, args []string) error {
+    if len(args) < 1 {
+      return errors.New("requires a color argument")
+    }
+    if myapp.IsValidColor(args[0]) {
+      return nil
+    }
+    return fmt.Errorf("invalid color specified: %s", args[0])
+  },
+  Run: func(cmd *cobra.Command, args []string) {
+    fmt.Println("Hello, World!")
+  },
+}
+```
+
+## Example
+
+In the example below, we have defined three commands. Two are at the top level
+and one (cmdTimes) is a child of one of the top commands. In this case the root
+is not executable, meaning that a subcommand is required. This is accomplished
+by not providing a 'Run' for the 'rootCmd'.
+
+We have only defined one flag for a single command.
+
+More documentation about flags is available at https://github.com/spf13/pflag
+
+```go
+package main
+
+import (
+  "fmt"
+  "strings"
+
+  "github.com/spf13/cobra"

+  }
+
+  var cmdTimes = &cobra.Command{
+    Use:   "times [string to echo]",
+    Short: "Echo anything to the screen more times",
+    Long: `echo things multiple times back to the user by providing
+a count and a string.`,
+    Args: cobra.MinimumNArgs(1),
+    Run: func(cmd *cobra.Command, args []string) {
+      for i := 0; i < echoTimes; i++ {
+        fmt.Println("Echo: " + strings.Join(args, " "))
+      }
+    },
+  }
+
+  cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")
+
+  var rootCmd = &cobra.Command{Use: "app"}
+  rootCmd.AddCommand(cmdPrint, cmdEcho)
+  cmdEcho.AddCommand(cmdTimes)
+  rootCmd.Execute()
+}
+```

+
+## Help Command
+
+Cobra automatically adds a help command to your application when you have subcommands.
+This will be called when a user runs 'app help'. Additionally, help will also
+support all other commands as input. Say, for instance, you have a command called
+'create' without any additional configuration; Cobra will work when 'app help
+create' is called.  Every command will automatically have the '--help' flag added.
+
+### Example
+
+The following output is automatically generated by Cobra. Nothing beyond the
+command and flag definitions are needed.
+
+    $ cobra help
+
+    Cobra is a CLI library for Go that empowers applications.
+    This application is a tool to generate the needed files
+    to quickly create a Cobra application.
+
+    Usage:
+      cobra [command]
+
+    Available Commands:
+      add         Add a command to a Cobra Application
+      help        Help about any command
+      init        Initialize a Cobra Application
+
+    Flags:
+      -a, --author string    author name for copyright attribution (default "YOUR NAME")
+          --config string    config file (default is $HOME/.cobra.yaml)
+      -h, --help             help for cobra
+      -l, --license string   name of license for the project
+          --viper            use Viper for configuration (default true)
+
+    Use "cobra [command] --help" for more information about a command.
+
+
+Help is just a command like any other. There is no special logic or behavior
+around it. In fact, you can provide your own if you want.
+
+### Defining your own help
+
+You can provide your own Help command or your own template for the default command to use
+with following functions:
+
+```go
+cmd.SetHelpCommand(cmd *Command)
+cmd.SetHelpFunc(f func(*Command, []string))
+cmd.SetHelpTemplate(s string)
+```
+
+The latter two will also apply to any children commands.
+
+## Usage Message
+
+When the user provides an invalid flag or invalid command, Cobra responds by
+showing the user the 'usage'.
+
+### Example
+You may recognize this from the help above. That's because the default help
+embeds the usage as part of its output.
+
+    $ cobra --invalid
+    Error: unknown flag: --invalid
+    Usage:
+      cobra [command]
+
+    Available Commands:
+      add         Add a command to a Cobra Application
+      help        Help about any command
+      init        Initialize a Cobra Application
+
+    Flags:
+      -a, --author string    author name for copyright attribution (default "YOUR NAME")
+          --config string    config file (default is $HOME/.cobra.yaml)
+      -h, --help             help for cobra
+      -l, --license string   name of license for the project
+          --viper            use Viper for configuration (default true)
+
+    Use "cobra [command] --help" for more information about a command.
+
+### Defining your own usage
+You can provide your own usage function or template for Cobra to use.
+Like help, the function and template are overridable through public methods:
+
+```go
+cmd.SetUsageFunc(f func(*Command) error)
+cmd.SetUsageTemplate(s string)
+```
+
+## Version Flag
+
+Cobra adds a top-level '--version' flag if the Version field is set on the root command.
+Running an application with the '--version' flag will print the version to stdout using
+the version template. The template can be customized using the
+`cmd.SetVersionTemplate(s string)` function.
+
+## PreRun and PostRun Hooks
+
+It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`.  The `Persistent*Run` functions will be inherited by children if they do not declare their own.  These functions are run in the following order:
+
+- `PersistentPreRun`
+- `PreRun`
+- `Run`
+- `PostRun`
+- `PersistentPostRun`
+
+An example of two commands which use all of these features is below.  When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`:
+
+```go
+package main
+
+import (
+  "fmt"
+
+  "github.com/spf13/cobra"
+)
+
+func main() {
+
+  var rootCmd = &cobra.Command{
+    Use:   "root [sub]",

+## Suggestions when "unknown command" happens
+
+Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
+
+```
+$ hugo srever
+Error: unknown command "srever" for "hugo"
+
+Did you mean this?
+        server
+
+Run 'hugo --help' for usage.
+```
+
+Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion.
+
+If you need to disable suggestions or tweak the string distance in your command, use:
+
+```go
+command.DisableSuggestions = true
+```
+
+or
+
+```go
+command.SuggestionsMinimumDistance = 1
+```
+
+You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example:
+
+```
+$ kubectl remove
+Error: unknown command "remove" for "kubectl"
+
+Did you mean this?
+        delete
+
+Run 'kubectl help' for usage.
+```
+
+## Generating documentation for your command
+
+Cobra can generate documentation based on subcommands, flags, etc. Read more about it in the [docs generation documentation](doc/README.md).
+
+## Generating shell completions
+
+Cobra can generate a shell-completion file for the following shells: bash, zsh, fish, PowerShell. If you add more information to your commands, these completions can be amazingly powerful and flexible.  Read more about it in [Shell Completions](shell_completions.md).

 ```go

 ## Q & A
 
-Q: Why is it called “Viper”?
+### Why is it called “Viper”?
 
 A: Viper is designed to be a [companion](http://en.wikipedia.org/wiki/Viper_(G.I._Joe))
 to [Cobra](https://github.com/spf13/cobra). While both can operate completely
 independently, together they make a powerful pair to handle much of your
 application foundation needs.

+
+### Does Viper support case sensitive keys?
+
+**tl;dr:** No.
+
+Viper merges configuration from various sources, many of which are either case insensitive or uses different casing than the rest of the sources (eg. env vars).
+In order to provide the best experience when using multiple sources, the decision has been made to make all keys case insensitive.
+
+There has been several attempts to implement case sensitivity, but unfortunately it's not that trivial. We might take a stab at implementing it in [Viper v2](https://github.com/spf13/viper/issues/772), but despite the initial noise, it does not seem to be requested that much.
+
+You can vote for case sensitivity by filling out this feedback form: https://forms.gle/R6faU74qPRPAzchZ9
+
+### Is it safe to concurrently read and write to a viper?
+
+No, you will need to synchronize access to the viper yourself (for example by using the `sync` package). Concurrent reads and writes can cause a panic.

+# Troubleshooting
+
+## Unmarshaling doesn't work
+
+The most common reason for this issue is improper use of struct tags (eg. `yaml` or `json`). Viper uses [github.com/mitchellh/mapstructure](https://github.com/mitchellh/mapstructure) under the hood for unmarshaling values which uses `mapstructure` tags by default. Please refer to the library's documentation for using other struct tags.
+
+## Cannot find package
+
+Viper installation seems to fail a lot lately with the following (or a similar) error:
+
+```
+cannot find package "github.com/hashicorp/hcl/tree/hcl1" in any of:
+/usr/local/Cellar/go/1.15.7_1/libexec/src/github.com/hashicorp/hcl/tree/hcl1 (from $GOROOT)
+/Users/user/go/src/github.com/hashicorp/hcl/tree/hcl1 (from $GOPATH)
+```
+
+As the error message suggests, Go tries to look up dependencies in `GOPATH` mode (as it's commonly called) from the `GOPATH`.
+Viper opted to use [Go Modules](https://github.com/golang/go/wiki/Modules) to manage its dependencies. While in many cases the two methods are interchangeable, once a dependency releases new (major) versions, `GOPATH` mode is no longer able to decide which version to use, so it'll either use one that's already present or pick a version (usually the `master` branch).
+
+The solution is easy: switch to using Go Modules.
+Please refer to the [wiki](https://github.com/golang/go/wiki/Modules) on how to do that.
