-## Expected files and resources

+  particularly important as many Official Repositories are some of the most
+  popular on Docker Hub.
 
-### A Git repository
+* Provide a channel for software vendors to redistribute up-to-date and
+  supported versions of their products. Organization accounts on Docker Hub can
+  also serve this purpose, without the careful review or restrictions on what
+  can be published.

+All Official Repositories contain a **User Feedback** section in their

-* an overview of the software contained in the image, similar to the
-introduction in a Wikipedia entry
-
-* a selection of links to outside resources that help to describe the software
-
-* a *mandatory* link to the `Dockerfile`
-
-#### How-to/usage
-
-A section that describes how to run and use the image, including common use
-cases and example `Dockerfile`s (if applicable). Try to provide clear, step-by-
-step instructions wherever possible.
-
-##### Issues and contributions
-
-In this section, point users to any resources that can help them contribute to
-the project. Include contribution guidelines and any specific instructions
-related to your development practices. Include a link to
-[Docker’s resources for contributors](https://docs.docker.com/contributing/contributing/).
-Be sure to include contact info, handles, etc. for official maintainers.
-
-Also include information letting users know where they can go for help and how
-they can file issues with the repo. Point them to any specific IRC channels,
-issue trackers, contacts, additional “how-to” information or other resources.
-
-### License
-
-Include a file, `LICENSE`, of any applicable license.  Docker recommends using
-the license of the software contained in the image, provided it allows Docker,
-Inc. to legally build and distribute the image. Otherwise, Docker recommends
-adopting the [Expat license](http://directory.fsf.org/wiki/License:Expat)
-(a.k.a., the MIT or X11 license).

-
-`Ruby on Rails is an open-source application framework written in Ruby. It emphasizes best practices such as convention over configuration, active record pattern, and the model-view-controller pattern.`

-`README.md`
-
-```markdown
-# What is Ruby on Rails
-
-Ruby on Rails, often simply referred to as Rails, is an open source web application framework which runs via the Ruby programming language. It is a full-stack framework: it allows creating pages and applications that gather information from the web server, talk to or query the database, and render templates out of the box. As a result, Rails features a routing system that is independent of the web server.

-
-# How to use this image
-
-## Create a `Dockerfile` in your rails app project
-
-    FROM rails:onbuild
-
-Put this file in the root of your app, next to the `Gemfile`.
-
-This image includes multiple `ONBUILD` triggers so that should be all that you need for most applications. The build will `ADD . /usr/src/app`, `RUN bundle install`, `EXPOSE 3000`, and set the default command to `rails server`.
-

+
+
+# Get the required software for Windows
+
+This page explains how to get the software you need to use a  a Windows Server
+2012 or Windows 8 machine for Docker development. Before you begin contributing
+you must have:
+
+- a GitHub account
+- Git for Windows (msysGit)
+- TDM-GCC, a compiler suite for Windows
+- MinGW (tar and xz)
+- Go language
+
+> **Note**: This installation prcedure refers to the `C:\` drive. If you system's main drive
+is `D:\` you'll need to substitute that in where appropriate in these
+instructions.
+
+### Get a GitHub account
+
+To contribute to the Docker project, you will need a <a
+href="https://github.com" target="_blank">GitHub account</a>. A free account is
+fine. All the Docker project repositories are public and visible to everyone.
+
+You should also have some experience using both the GitHub application and `git`
+on the command line. 
+
+## Install Git for Windows
+
+Git for Windows includes several tools including msysGit, which is a build
+environment. The environment contains the tools you need for development such as
+Git and a Git Bash shell.
+

+
+2. Click **Download**.
+
+	Windows prompts you to save the file to your machine.
+
+3. Run the saved file.
+
+	The system displays the **Git Setup** wizard.
+
+4. Click the **Next** button to move through the wizard and accept all the defaults.
+
+5. Click **Finish** when you are done.
+
+## Installing TDM-GCC
+
+TDM-GCC is a compiler suite for Windows. You'll use this suite to compile the
+Docker Go code as you develop.
+
+1. Browse to
+   [tdm-gcc download page](http://tdm-gcc.tdragon.net/download).
+
+2. Click on the lastest 64-bit version of the package.
+
+	Windows prompts you to save the file to your machine
+
+3. Set up the suite by running the downloaded file.
+
+	The system opens the **TDM-GCC Setup** wizard.
+	
+4. Click **Create**.
+
+5. Click the **Next** button to move through the wizard and accept all the defaults.
+
+6. Click **Finish** when you are done.
+
+
+## Installing MinGW (tar and xz)
+
+MinGW is a minimalist port of the GNU Compiler Collection (GCC). In this
+procedure, you first download and install the MinGW installation manager. Then,
+you use the manager to install the `tar` and `xz` tools from the collection.
+
+1. Browse to MinGW 
+   [SourceForge](http://sourceforge.net/projects/mingw/).
+
+2. Click **Download**.
+
+	 Windows prompts you to save the file to your machine
+
+3. Run the downloaded file.
+
+   The system opens the **MinGW Installation Manager Setup Tool**
+
+4. Choose **Install**  install the MinGW Installation Manager.
+
+5. Press **Continue**.
+
+	The system installs and then opens the MinGW Installation Manager.
+	
+6. Press **Continue** after the install completes to open the manager.
+
+7. Select **All Packages > MSYS Base System** from the left hand menu.
+
+	The system displays the available packages.
+
+8. Click on the the **msys-tar bin** package and choose **Mark for Installation**.
+
+9. Click on the **msys-xz bin** package and choose **Mark for Installation**.
+  
+10. Select **Installation > Apply Changes**, to install the selected packages.
+
+	The system displays the **Schedule of Pending Actions Dialog**.
+
+    ![windows-mingw](/project/images/windows-mingw.png)
+    
+11. Press **Apply**
+
+	MingGW installs the packages for you.
+
+12. Close the dialog and the MinGW Installation Manager.
+
+
+## Set up your environment variables
+
+You'll need to add the compiler to your `Path` environment variable. 
+
+1. Open the **Control Panel**.
+
+2. Choose **System and Security > System**. 
+
+3. Click the **Advanced system settings** link in the sidebar.
+
+	The system opens the **System Properties** dialog.
+
+3. Select the **Advanced** tab.
+
+4. Click **Environment Variables**. 
+
+	The system opens the **Environment Variables dialog** dialog.
+
+5. Locate the **System variables** area and scroll to the **Path**
+   variable.
+
+    ![windows-mingw](/project/images/path_variable.png)
+
+6. Click **Edit** to edit the variable (you can also double-click it).
+
+	The system opens the **Edit System Variable** dialog.
+
+7. Make sure the `Path` includes `C:\TDM-GCC64\bin` 
+
+	 ![include gcc](/project/images/include_gcc.png)
+	 
+	 If you don't see `C:\TDM-GCC64\bin`, add it.
+		
+8. Press **OK** to close this dialog.
+	
+9. Press **OK** twice to close out of the remaining dialogs.
+
+## Install Go and cross-compile it
+
+In this section, you install the Go language. Then, you build the source so that it can cross-compile for `linux/amd64` architectures.
+
+1. Open [Go Language download](http://golang.org/dl/) page in your browser.
+
+2. Locate and click the latest `.msi` installer.
+
+	The system prompts you to save the file.
+
+3. Run the installer.
+
+	The system opens the **Go Programming Langauge Setup** dialog.
+
+4. Select all the defaults to install.
+
+5. Press **Finish** to close the installation dialog.
+
+6. Start a command prompt.
+
+7. Change to the Go `src` directory.
+
+		cd c:\Go\src 
+
+8. Set the following Go variables
+
+		c:\Go\src> set GOOS=linux
+		c:\Go\src> set GOARCH=amd64
+     
+9. Compile the source.
+
+		c:\Go\src> make.bat
+    
+	Compiling the source also adds a number of variables to your Windows environment.
+
+## Get the Docker repository
+
+In this step, you start a Git `bash` terminal and get the Docker source code from
+Github. 
+
+1. Locate the **Git Bash** program and start it.
+
+	Recall that **Git Bash** came with the Git for Windows installation.  **Git
+	Bash** just as it sounds allows you to run a Bash terminal on Windows.
+	
+	![Git Bash](/project/images/git_bash.png)
+
+2. Change to the root directory.
+
+		$ cd /c/
+				
+3. Make a `gopath` directory.
+
+		$ mkdir gopath
+
+4. Go get the `docker/docker` repository.
+
+		$ go.exe get github.com/docker/docker package github.com/docker/docker
+        imports github.com/docker/docker
+        imports github.com/docker/docker: no buildable Go source files in C:\gopath\src\github.com\docker\docker
+
+	In the next steps, you create environment variables for you Go paths.
+	
+5. Open the **Control Panel** on your system.
+
+6. Choose **System and Security > System**. 
+
+7. Click the **Advanced system settings** link in the sidebar.
+
+	The system opens the **System Properties** dialog.
+
+8. Select the **Advanced** tab.
+

+
+10. Locate the **System variables** area and scroll to the **Path**
+   variable.
+
+11. Click **New**.
+
+	Now you are going to create some new variables. These paths you'll create in the next procedure; but you can set them now.
+
+12. Enter `GOPATH` for the **Variable Name**.
+
+13. For the **Variable Value** enter the following:
+ 
+		C:\gopath;C:\gopath\src\github.com\docker\docker\vendor
+		
+	
+14. Press **OK** to close this dialog.
+
+	The system adds `GOPATH` to the list of **System Variables**.

+| `*/*/temp*`    | Exclude files starting with name `temp` from any subdirectory that is two levels below the root directory. For example, the file `/somedir/subdir/temporary.txt` is ignored. |
+| `temp?`        | Exclude the files that match the pattern in the root directory. For example, the files `tempa`, `tempb` in the root directory are ignored.                               |
+| `*.md `        | Exclude all markdown files.                                                                                                                                                  |

+
+The placement of  `!` exception rules influences the matching algorithm; the
+last line of the `.dockerignore` that matches a particular file determines
+whether it is included or excluded. In the above example, the `LICENSE.md` file
+matches both the  `*.md` and `!LICENSE.md` rule. If you reverse the lines in the
+example:
+
+```
+    */temp*
+    */*/temp*
+    temp?
+    !LICENCSE.md
+    *.md
+```
+
+The build would exclude `LICENSE.md` because the last `*.md` rule adds all
+Markdown files back onto the ignore list. The `!LICENSE.md` rule has no effect
+because the subsequent `*.md` rule overrides it.
+
+You can even use the  `.dockerignore` file to ignore the `Dockerfile` and
+`.dockerignore` files. This is useful if you are copying files from the root of
+the build context into your new container but do not want to include the
+`Dockerfile` or `.dockerignore` files (e.g. `ADD . /someDir/`).
