-## Upgrade from v1
-
-`v2` of this action includes significant updates and now uses Docker [Buildx](https://github.com/docker/buildx). It's
-also rewritten as a [typescript-action](https://github.com/actions/typescript-action/) to be as close as possible
-of the [GitHub Runner](https://github.com/actions/virtual-environments) during its execution.
-
-[Upgrade notes](UPGRADE.md) with many [usage examples](#advanced-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).

 ### 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).
+
+The git reference will be based on the [event that triggered your workflow](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows)
+and will result in the following context: `https://github.com/<owner>/<repo>.git#<ref>`.

-# 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` 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
-* Rename `build_args` input to `build-args` for consistency with other Docker build tools
-* 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

 # 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)
+This page has moved to [Docker Docs website](https://docs.docker.com/build/ci/github-actions/examples/#secrets)
-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
-        uses: actions/checkout@v2
-      -
-        name: Set up QEMU
-        uses: docker/setup-qemu-action@v1
-      -
-        name: Set up Docker Buildx
-        uses: docker/setup-buildx-action@v1
-      -
-        name: Build
-        uses: docker/build-push-action@v2
-        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"}` |
-
-> :bulb: All quote signs need to be doubled for escaping.
