 and much improved functionality that can be powerful tools for improving your
 builds' performance or reusability of your Dockerfiles, and it also introduces
 support for complex scenarios.

+## Docker Build features
+
+Docker Build is way more than your `docker build` command and is not only about packaging your code, it’s a whole ecosystem of tools and features that support you not only with common workflow tasks but also provides you with support for more complex and advanced scenarios.
+Here’s an overview of all the use cases with which Build can support you:
+
+### Building your images
+
+* **Packaging your software**  
+Bundle and package your code to run anywhere, from your local Docker Desktop, to Docker Engine and Kubernetes on the cloud.  
+To get started with Build, see the [Hello Build](hellobuild.md) page.
+
+* **Choosing a build driver**  
+Run Buildx with different configurations depending on the scenario you are working on, regardless of whether you are using your local machine or a remote compute cluster, all from the comfort of your local working environment.  
+Here’s a quick overview of the drivers and the use cases they support:  
+    * `docker`– use the default built-in builder to get started quickly.
+    * `docker-container` – spin up a dedicated builder in a docker container to unlock more advanced features like advanced caching, and multi-arch images.
+    * `kubernetes`– connect to your Kubernetes cluster to unlock more features and to run your builds at scale.
+    * `remote`–  manually manage your own BuildKit builder and connect directly to it.
+
+* **Optimizing builds with cache management**  
+Improve build performance by using a persistent shared build cache to avoid repeating costly operations such as package installations, downloading files from the internet, or code build steps.
+
+* **Creating build-once, run-anywhere with multi-architecture builds**
+Collaborate across platforms with one build artifact.  
+See [Build multi platform images](buildx/index.md/#build-multi-platform-images).
+
+### Automating your builds
+
+* **Integrating with GitHub**  
+Automate your image builds to run in GitHub actions using the official docker build actions. See:  
+    * [GitHub Action to build and push Docker images with Buildx](https://github.com/docker/build-push-action).
+    * [GitHub Action to extract metadata from Git reference and GitHub events](https://github.com/docker/metadata-action/).
+
+* **Orchestrating builds across complex projects together**  
+Connect your builds together and easily parameterize your images using buildx bake.  
+<!--replace when Bake content is onboarded -->
+See [High-level build options](buildx/index.md/#high-level-build-options)
+
+### Customizing your Builds
+
+* **Select your build output format**  
+Choose from a variety of available output formats, to export any artifact you like from BuildKit, not just docker images.  
+See [Set the export action for the build result](../engine/reference/commandline/buildx_build.md/#output).
+
+* **Managing build secrets**  
+Securely access protected repositories and resources at build time without leaking data into the final build or the cache.
+
+### Extending BuildKit
+
+* **Custom syntax on Dockerfile**  
+Use experimental versions of the Dockerfile frontend, or even just bring your own to BuildKit using the power of custom frontends.  
+See also the [Syntax directive](../engine/reference/builder/#syntax).
+
+* **Configure BuildKit**  
+Take a deep dive into the internal BuildKit configuration to get the most out of your builds.  
+See also [`buildkitd.toml`](https://github.com/moby/buildkit/blob/master/docs/buildkitd.toml.md), the configuration file for `buildkitd`.
