-## Upgrade from v1
-
-`v2` of this action includes significant updates and now uses Docker [Buildx](https://github.com/docker/buildx). It
-works with 3 new actions ([login](https://github.com/docker/login-action), [setup-buildx](https://github.com/docker/setup-buildx-action)
-and [setup-qemu](https://github.com/docker/setup-qemu-action)) that we have created. It's also rewritten as a
-[typescript-action](https://github.com/actions/typescript-action/) to be as closed as possible of the
-[GitHub Runner](https://github.com/actions/virtual-environments) during its execution.
-
-[Upgrade notes](UPGRADE.md) and many [usage examples](#usage) have been added to handle most use cases but `v1` is
-still available through [`releases/v1` branch](https://github.com/docker/build-push-action/tree/releases/v1).
-

 ## Usage
 
-This action uses our [setup-buildx](https://github.com/docker/setup-buildx-action) action that extends the
-`docker build` command named [buildx](https://github.com/docker/buildx) with the full support of the features
-provided by [Moby BuildKit](https://github.com/moby/buildkit) builder toolkit. This includes multi-arch build,
-build-secrets, remote cache, etc. and different builder deployment/namespacing options.
+In the examples below we are also 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.
 
 ### Git context
 
-The default behavior of this action is to use the [Git context invoked](https://github.com/docker/build-push-action/blob/master/src/context.ts#L31-L35)
-by your workflow.
+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
+check out the repository because this will be done directly by [BuildKit](https://github.com/moby/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>`.

+Default Git context can also be provided using the [Handlebars template](https://handlebarsjs.com/guide/)

 ## Advanced usage
 
-### Push to multi-registries
-
-The following workflow will connect you to [DockerHub](https://github.com/docker/login-action#dockerhub)
-and [GitHub Container Registry](https://github.com/docker/login-action#github-container-registry) and push the
-image to these registries.

-### Export image to Docker
-
-You may want your build result to be available in the Docker client through `docker images` to be able to use it
-in another step of your workflow:

-### Leverage GitHub cache
-
-You can leverage [GitHub cache](https://docs.github.com/en/actions/configuring-and-managing-workflows/caching-dependencies-to-speed-up-workflows)
-using [actions/cache](https://github.com/actions/cache) with this action:

-            cache-to: type=local,dest=/tmp/.buildx-cache
-  ```
-</details>
-
-> If you want to [export layers for all stages](https://github.com/docker/buildx#--cache-tonametypetypekeyvalue),
-> you have to specify `mode=max` attribute in `cache-to`.
-
-### Complete workflow
-
-If you come from [`v1`](https://github.com/docker/build-push-action/tree/releases/v1#readme) and want an
-"automatic" tag management through Git reference and [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)
-for labels, you will have to do it in a dedicated step.
-
-The following workflow with the `Prepare` step will generate some [outputs](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjobs_idoutputs)
-to handle tags and labels based on GitHub actions events.
-
-This is just an example to show many cases that you might want to use and that you will have to adapt according
-to your needs:

-Next you can test pushing with [containerd action](https://github.com/crazy-max/ghaction-setup-containerd) using the
-following workflow. If it works then open an issue on [buildkit](https://github.com/moby/buildkit) repository.

+in your tag:

+or a cache reference:
+
+```
+#10 importing cache manifest from ghcr.io/My-Org/repo:main
+#10 ERROR: invalid reference format: repository name must be lowercase
+```
+
+To fix this issue you can use our [metadata action](https://github.com/docker/metadata-action)
+to generate sanitized tags:
+
+```yaml
+- name: Docker meta
+  id: meta
+  uses: docker/metadata-action@v4

+    context: .
+    push: true
+    tags: ${{ steps.meta.outputs.tags }}
+```
+
+Or a dedicated step to sanitize the slug:
+
+```yaml
+- name: Sanitize repo slug
+  uses: actions/github-script@v6
+  id: repo_slug
+  with:
+    result-encoding: string

-# Upgrade notes
-
-## 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`](https://github.com/docker/buildx#---platformvaluevalue) input to support multi-platform builds
-* Add [`allow`](https://github.com/docker/buildx#--allowentitlement) input
-* Add [`load`](https://github.com/docker/buildx#--load) input
-* Add [`outputs`](https://github.com/docker/buildx#-o---outputpath-typetypekeyvalue) input
-* Add [`cache-from`](https://github.com/docker/buildx#--cache-fromnametypetypekeyvalue) input (`cache_froms` removed)
-* Add [`cache-to`](https://github.com/docker/buildx#--cache-tonametypetypekeyvalue) input
-* Add `secrets` input
-* Review `tags` input
-* Remove `repository` input. See [Simple workflow](#simple-workflow) for migration
-* Remove `username`, `password` and `registry` inputs. Login support moved to [docker/login-action](https://github.com/docker/login-action) repo
-* Remove `tag_with_sha`, `tag_with_ref`, `add_git_labels` inputs. See [Tags with ref and Git labels](#tags-with-ref-and-git-labels) for migration
-* Handle Git context
-* Add `digest` output

+
+## 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).
+
+```yaml

+    runs-on: ubuntu-latest

+```
+
+## Registry cache
+
+You can import/export cache from a cache manifest or (special) image configuration on the registry with the
+[`type=registry` cache exporter](https://github.com/moby/buildkit/tree/master#registry-push-image-and-cache-separately).
+
+```yaml
+name: ci
+

+```
+
+## GitHub cache
+
+### 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:
+      - 'main'
+
+jobs:
+  docker:
+    runs-on: ubuntu-latest
+    steps:
+      -
+        name: Checkout
+        uses: actions/checkout@v3
+      -
+        name: Set up QEMU
+        uses: docker/setup-qemu-action@v2
+      -
+        name: Set up Docker Buildx
+        uses: docker/setup-buildx-action@v2
+      -
+        name: Build
+        uses: docker/build-push-action@v3
+        with:
+          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"}` |
