 ### Run the unit- and integration-tests
 
-Running tests:
-
-```bash
-make test
-```
-
-This runs all unit and integration tests, in a containerized environment.
-Locally, every package can be tested separately with standard Go tools, but
-integration tests are skipped if local user doesn't have enough permissions or
-worker binaries are not installed.
-
-```bash
-# run unit tests only
-make test-unit
-
-# run integration tests only
-make test-integration
-
-# test a specific package
-TESTPKGS=./bake make test
-
-# run all integration tests with a specific worker
-TESTFLAGS="--run=//worker=remote -v" make test-integration
-
-# run a specific integration test
-TESTFLAGS="--run /TestBuild/worker=remote/ -v" make test-integration
-
-# run a selection of integration tests using a regexp
-TESTFLAGS="--run /TestBuild.*/worker=remote/ -v" make test-integration
-```
-
-> **Note**
->
-> Set `TEST_KEEP_CACHE=1` for the test framework to keep external dependant
-> images in a docker volume if you are repeatedly calling `make test`. This
-> helps to avoid rate limiting on the remote registry side.
-
-> **Note**
->
-> Set `TEST_DOCKERD=1` for the test framework to enable the docker workers,
-> specifically the `docker` and `docker-container` drivers.
->
-> The docker tests cannot be run in parallel, so require passing `--parallel=1`
-> in `TESTFLAGS`.
-
-> **Note**
->
-> If you are working behind a proxy, you can set some of or all
-> `HTTP_PROXY=http://ip:port`, `HTTPS_PROXY=http://ip:port`, `NO_PROXY=http://ip:port`
-> for the test framework to specify the proxy build args.

 # Installing
 
-Using `buildx` with Docker requires Docker engine 19.03 or newer.
+Using `buildx` as a docker CLI plugin requires using Docker 19.03 or newer.
+A limited set of functionality works with older versions of Docker when
+invoking the binary directly.
 
-> **Warning**
+## Docker
->
-> Using an incompatible version of Docker may result in unexpected behavior,

-> recent versions of BuildKit.
 
-## Windows and macOS
+`buildx` comes bundled with Docker Desktop and in latest
+[Docker CE packages](https://docs.docker.com/engine/install/), but may not be
+included in third-party software components (in which case follow the
+[binary release](#binary-release) instructions).
 
-Docker Buildx is included in [Docker Desktop](https://docs.docker.com/desktop/)
+## Binary release
-for Windows and macOS.
 
-## Linux packages
+You can also download the latest `buildx` binary from the
+[GitHub releases](https://github.com/docker/buildx/releases/latest) page, copy
+it to `~/.docker/cli-plugins` folder with name `docker-buildx` and change the

-You can also download the latest binary from the [GitHub releases page](https://github.com/docker/buildx/releases/latest).

-Rename the relevant binary and copy it to the destination matching your OS:

-| -------- | -------------------- | -----------------------------------------|

-| Windows  | `docker-buildx.exe`  | `%USERPROFILE%\.docker\cli-plugins`      |
-
-Or copy it into one of these folders for installing it system-wide.

 ## High-level build options
 
-See [High-level builds with Bake](https://docs.docker.com/build/bake/) for more details.
+Buildx also aims to provide support for high-level build concepts that go beyond
+invoking a single build command. We want to support building all the images in
+your application together and let the users define project specific reusable
+build flows that can then be easily invoked by anyone.
+
+BuildKit efficiently handles multiple concurrent build requests and
+de-duplicating work. The build commands can be combined with general-purpose
+command runners (for example, `make`). However, these tools generally invoke
+builds in sequence  and therefore cannot leverage the full potential of BuildKit
+parallelization, or combine BuildKit’s output for the user. For this use case,
+we have added a command called [`docker buildx bake`](docs/reference/buildx_bake.md).
+
+The `bake` command supports building images from compose files, similar to
+[`docker-compose build`](https://docs.docker.com/compose/reference/build/),
+but allowing all the services to be built concurrently as part of a single
+request.
+
+There is also support for custom build rules from HCL/JSON files allowing
+better code reuse and different target groups. The design of bake is in very
+early stages and we are looking for feedback from users.

-# Debug monitor
-
-To assist with creating and debugging complex builds, Buildx provides a
-debugger to help you step through the build process and easily inspect the
-state of the build environment at any point.
-
-> **Note**
->
-> The debug monitor is a new experimental feature in recent versions of Buildx.
-> There are rough edges, known bugs, and missing features. Please try it out
-> and let us know what you think!
-
-## Starting the debugger
-
-To start the debugger, first, ensure that `BUILDX_EXPERIMENTAL=1` is set in
-your environment.
-
-```console
-$ export BUILDX_EXPERIMENTAL=1
-```
-
-To start a debug session for a build, you can use the `buildx debug` command with `--invoke` flag to specify a command to launch in the resulting image.
-`buildx debug` command provides `buildx debug build` subcommand that provides the same features as the normal `buildx build` command but allows launching the debugger session after the build.
-
-Arguments available after `buildx debug build` are the same as the normal `buildx build`.
-
-```console
-$ docker buildx debug --invoke /bin/sh build .

-
-This launches a `/bin/sh` process in the final stage of the image, and allows
-you to explore the contents of the image, without needing to export or load the
-image outside of the builder.
-
-For example, you can use `ls` to see the contents of the image:
-
-```console
-/ # ls
-bin    etc    lib    mnt    proc   run    srv    tmp    var
-dev    home   media  opt    root   sbin   sys    usr    work
-```
-
-Optional long form allows you specifying detailed configurations of the process. 
-It must be CSV-styled comma-separated key-value pairs.
-Supported keys are `args` (can be JSON array format), `entrypoint` (can be JSON array format), `env` (can be JSON array format), `user`, `cwd` and `tty` (bool).
-
-Example:
-
-```
-$ docker buildx debug --invoke 'entrypoint=["sh"],"args=[""-c"", ""env | grep -e FOO -e AAA""]","env=[""FOO=bar"", ""AAA=bbb""]"' build .
-```
-
-#### `on` flag
-
-If you want to start a debug session when a build fails, you can use
-`--on=error` to start a debug session when the build fails.

-```
-
-You can then use the commands available in [monitor mode](#monitor-mode) to
-start and observe the build.
-
-## Monitor mode
-
-By default, when debugging, you'll be dropped into a shell in the final stage.
-
-When you're in a debug shell, you can use the `Ctrl-a-c` key combination (press
-`Ctrl`+`a` together, lift, then press `c`) to toggle between the debug shell
-and the monitor mode. In monitor mode, you can run commands that control the
-debug environment.
-
-```console
-(buildx) help
-Available commands are:
-  attach	attach to a buildx server or a process in the container
-  disconnect	disconnect a client from a buildx server. Specific session ID can be specified an arg
-  exec		execute a process in the interactive container
-  exit		exits monitor
-  help		shows this message. Optionally pass a command name as an argument to print the detailed usage.
-  kill		kill buildx server
-  list		list buildx sessions
-  ps		list processes invoked by "exec". Use "attach" to attach IO to that process
-  reload	reloads the context and build it
-  rollback	re-runs the interactive container with the step's rootfs contents
-```
-
-## Build controllers
-
-Debugging is performed using a buildx "controller", which provides a high-level
-abstraction to perform builds. By default, the local controller is used for a
-more stable experience which runs all builds in-process. However, you can also
-use the remote controller to detach the build process from the CLI.
-
-To detach the build process from the CLI, you can use the `--detach=true` flag with
-the build command.
-
-```console
-$ docker buildx debug --invoke /bin/sh build --detach=true .
-```
-
-If you start a debugging session using the `--invoke` flag with a detached
-build, then you can attach to it using the `buildx debug` command to
-immediately enter the monitor mode.

-```console
