 ## Usage
 
-By default, this action uses the [Git context](#git-context) so you don't need to use the
-[`actions/checkout`](https://github.com/actions/checkout/) action to checkout the repository because this will be
-done directly by buildkit. The git reference will be based on the [event that triggered your workflow](https://docs.github.com/en/actions/reference/events-that-trigger-workflows)
-and will result in the following context: `https://github.com/<owner>/<repo>.git#<ref>`.
+In the examples below we are also using 3 other actions:
 
-You can provide a subdirectory to the [Git context](#git-context) by using the following [Handlebars template](https://handlebarsjs.com/guide/) expression `{{defaultContext}}`:
-
-```yaml
-      -
-        name: Build and push
-        id: docker_build
-        uses: docker/build-push-action@v2
-        with:
-          context: {{defaultContext}}:docker
-          push: true
-          tags: user/app:latest
-```
-
-Be careful because **any file mutation in the steps that precede the build step will be ignored, including processing of the `.dockerignore` file** since
-the context is based on the git reference. However, you can use the [Path context](#path-context) using the
-[`context` input](#inputs) alongside the [`actions/checkout`](https://github.com/actions/checkout/) action to remove
-this restriction.
-
-In the examples below we are using 3 other actions:
-
-* [`setup-buildx`](https://github.com/docker/setup-buildx-action) action will create and boot a builder using by 
-default the `docker-container` [builder driver](https://github.com/docker/buildx/blob/master/docs/reference/buildx_create.md#driver).
-This is **not required but recommended** using it to be able to build multi-platform images, export cache, etc.
-* [`setup-qemu`](https://github.com/docker/setup-qemu-action) action can be useful if you want
-to add emulation support with QEMU to be able to build against more platforms. 
-* [`login`](https://github.com/docker/login-action) action will take care to log in against a Docker registry.
+* [`setup-buildx`](https://github.com/docker/setup-buildx-action) action will
+  create and boot a builder using by default the [`docker-container` driver](https://docs.docker.com/build/building/drivers/docker-container/).
+  This is **not required but recommended** using it to be able to build
+  multi-platform images, export cache, etc.
+* [`setup-qemu`](https://github.com/docker/setup-qemu-action) action can be
+  useful if you want to add emulation support with QEMU to be able to build
+  against more platforms.

 ### Git context
 
+By default, this action uses the [Git context](https://docs.docker.com/engine/reference/commandline/build/#git-repositories),
+so you don't need to use the [`actions/checkout`](https://github.com/actions/checkout/)
+action to check out the repository as this will be done directly by [BuildKit](https://github.com/moby/buildkit).

-## v1 to v2
-
-* Input `path` is now called `context` for consistency with other Docker build tools
-* `path` defaults to current git repository so checkout action is not required in a workflow
-* Rename `dockerfile` input to `file` for consistency with other Docker build tools
-* Rename `always_pull` input to `pull` for consistency with other Docker build tools
-* Add `builder` input to be able to choose a builder instance through our [setup-buildx action](https://github.com/docker/setup-buildx-action)
-* Add `platforms` input to support multi-platform builds
-* Add `allow` input
-* Add `load` input
-* Add `outputs` input
-* Add `cache-from` input (`cache_froms` removed)
-* Add `cache-to` input

-## Inline cache
-
-In most cases you want to use the [`type=inline` cache exporter](https://github.com/moby/buildkit#inline-push-image-and-cache-together).
-However, note that the `inline` cache exporter only supports `min` cache mode. To enable `max` cache mode, push the
-image and the cache separately by using the `registry` cache exporter as shown in the [next example](#registry-cache).

-
-You can import/export cache from a cache manifest or (special) image configuration on the registry with the

-### Cache backend API
-
-> :test_tube: This cache exporter is considered EXPERIMENTAL until further notice. Please provide feedback on
-> [BuildKit repository](https://github.com/moby/buildkit) if you encounter any issues.
-
-Since [buildx 0.6.0](https://github.com/docker/buildx/releases/tag/v0.6.0) and [BuildKit 0.9.0](https://github.com/moby/buildkit/releases/tag/v0.9.0),
-you can use the [`type=gha` cache exporter](https://github.com/moby/buildkit/tree/master#github-actions-cache-experimental).
-
-GitHub Actions cache exporter backend uses the [GitHub Cache API](https://github.com/tonistiigi/go-actions-cache/blob/master/api.md)
-to fetch and upload cache blobs. That's why this type of cache should be exclusively used in a GitHub Action workflow
-as the `url` (`$ACTIONS_CACHE_URL`) and `token` (`$ACTIONS_RUNTIME_TOKEN`) attributes are populated when a workflow
-is started.

 # Secrets
 
-In the following example we will expose and use the [GITHUB_TOKEN secret](https://docs.github.com/en/actions/reference/authentication-in-a-workflow#about-the-github_token-secret)
-as provided by GitHub in your workflow.
-
-First let's create our `Dockerfile` to use our secret:
-
-```Dockerfile
-#syntax=docker/dockerfile:1.2
-
-FROM alpine
-RUN --mount=type=secret,id=github_token \
-  cat /run/secrets/github_token
-```
-
-As you can see we have named our secret `github_token`. Here is the workflow you can use to expose this secret using
-the [`secrets` input](../../README.md#inputs):
-
-```yaml
-name: ci
-
-on:
-  push:
-    branches:
-      - 'master'
-
-jobs:
-  docker:
-    runs-on: ubuntu-latest
-    steps:
-      -
-        name: Checkout

-      -

-          context: .
-          platforms: linux/amd64,linux/arm64
-          tags: user/app:latest
-          secrets: |
-            "github_token=${{ secrets.GITHUB_TOKEN }}"
-```
-
-> :bulb: You can also expose a secret file to the build with [`secret-files`](../../README.md#inputs) input:
-> ```yaml
-> secret-files: |
->   "MY_SECRET=./secret.txt"
-> ```
-
-If you're using [GitHub secrets](https://docs.github.com/en/actions/reference/encrypted-secrets) and need to handle
-multi-line value, you will need to place the key-value pair between quotes:
-
-```yaml
-secrets: |
-  "MYSECRET=${{ secrets.GPG_KEY }}"
-  GIT_AUTH_TOKEN=abcdefghi,jklmno=0123456789
-  "MYSECRET=aaaaaaaa
-  bbbbbbb
-  ccccccccc"
-  FOO=bar
-  "EMPTYLINE=aaaa
-  
-  bbbb
-  ccc"
-  "JSON_SECRET={""key1"":""value1"",""key2"":""value2""}"
-```
-
-| Key                | Value                                            |
-|--------------------|--------------------------------------------------|
-| `MYSECRET`         | `***********************` |
-| `GIT_AUTH_TOKEN`   | `abcdefghi,jklmno=0123456789` |
-| `MYSECRET`         | `aaaaaaaa\nbbbbbbb\nccccccccc` |
-| `FOO`              | `bar` |
-| `EMPTYLINE`        | `aaaa\n\nbbbb\nccc` |
-| `JSON_SECRET`      | `{"key1":"value1","key2":"value2"}` |
