+
+This action also handles a bake definition file that can be used with the
+[Docker Bake action](https://github.com/docker/bake-action). You just have to declare an empty target named
+`ghaction-docker-meta` and inherit from it.
+
+```hcl
+// docker-bake.hcl
+target "ghaction-docker-meta" {}
+
+target "build" {
+  inherits = ["ghaction-docker-meta"]
+  context = "./"
+  dockerfile = "Dockerfile"
+  platforms = ["linux/amd64", "linux/arm/v6", "linux/arm/v7", "linux/arm64", "linux/386", "linux/ppc64le"]

+
+```yaml
+flavor: |
+  latest=auto
+  prefix=
+  suffix=
+```
+
+* `latest=<auto|true|false>`: Handle [latest tag](#latest-tag) (default `auto`)
+* `prefix=<string>`: A global prefix for each generated tag
+* `suffix=<string>`: A global suffix for each generated tag
+
+## `tags` input
+
+`tags` is the core input of this action as everything related to it will reflect the output metadata. This one is in
+the form of a key-value pair list in CSV format to remove limitations intrinsically linked to GitHub Actions
+(only string format is handled in the input fields). Here is an example:
+
+```yaml
+tags: |
+  type=schedule
+  type=ref,event=branch
+  type=ref,event=pr
+  type=semver,pattern={{version}}
+  type=semver,pattern={{major}}.{{minor}}
+  type=semver,pattern={{major}}
+  type=sha
+```
+
+Each entry is defined by a `type`, which are:
+
+* [`type=schedule`](#typeschedule)
+* [`type=semver`](#typesemver)
+* [`type=match`](#typematch)
+* [`type=edge`](#typeedge)
+* [`type=ref`](#typeref)
+* [`type=raw`](#typeraw)
+* [`type=sha`](#typesha)
+
+And global attributes:
+
+* `enable=<true|false>` enable this entry (default `true`)
+* `priority=<number>` priority to manage the order of tags
+* `prefix=<string>` add prefix
+* `suffix=<string>` add suffix
+
+Default entries if `tags` input is empty:
+
+```yaml
+tags: |
+  type=schedule
+  type=ref,event=branch
+  type=ref,event=tag
+  type=ref,event=pr
+```
+
+### `type=schedule`
+
+```yaml
+tags: |
+  # minimal
+  type=schedule
+  # default
+  type=schedule,pattern=nightly
+  # handlebars
+  type=schedule,pattern={{date 'YYYYMMDD'}}
+```
+
+Will be used on [schedule event](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#schedule).
+
+`pattern` is a specially crafted attribute to support [Handlebars template](https://handlebarsjs.com/guide/) with
+the following expressions:
+* `date 'format'` ; render date by its [moment format](https://momentjs.com/docs/#/displaying/format/)
+
+| Pattern                  | Output               |
+|--------------------------|----------------------|
+| `nightly`                | `nightly`            |
+| `{{date 'YYYYMMDD'}}`    | `20210326`           |
+
+Extended attributes and default values:
+
+```yaml
+tags: |
+  type=schedule,enable=true,priority=1000,prefix=,suffix=,pattern=nightly
+```
+
+### `type=semver`
+
+```yaml
+tags: |
+  # minimal
+  type=semver,pattern={{version}}
+  # use custom value instead of git tag
+  type=semver,pattern={{version}},value=v1.0.0
+```
+
+Will be used on a [push tag event](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#push)
+and requires a valid Git tag [semver](https://semver.org/) but you can also use a custom value through `value`
+attribute.
+
+`pattern` attribute supports [Handlebars template](https://handlebarsjs.com/guide/) with the following expressions:
+* `raw` ; the actual semver
+* `version` ; shorthand for `{{major}}.{{minor}}.{{patch}}` (can include pre-release)
+* `major` ; major version identifier
+* `minor` ; minor version identifier
+* `patch` ; patch version identifier

+  # use custom value instead of git tag

+```
+
+Can create a regular expression for matching Git tag with a pattern and capturing group. Will be used on a
+[push tag event](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#push) but you can also use
+a custom value through `value` attribute.

+Extended attributes and default values:
+
+```yaml

+  type=match,enable=true,priority=800,prefix=,suffix=,pattern=,group=0,value=
+```
+
+### `type=edge`
+
+```yaml
+tags: |
+  # minimal
+  type=edge
+  # define default branch
+  type=edge,branch=main
+```
+
+An `edge` tag reflects the last commit of the active branch on your Git repository. I usually prefer to use `edge`
+as a Docker tag for a better distinction or common pattern. This is also used by official images
+like [Alpine](https://hub.docker.com/_/alpine).
+
+Extended attributes and default values:
+
+```yaml
+tags: |
+  type=edge,enable=true,priority=700,prefix=,suffix=,branch=$repo.default_branch
+```
+
+### `type=ref`
+
+```yaml
+tags: |
+  # branch event
+  type=ref,event=branch
+  # tag event
+  type=ref,event=tag
+  # pull request event
+  type=ref,event=pr
+```
+
+This type handles Git ref (or reference) for the following events:
+* `branch` ; eg. `refs/heads/master`
+* `tag` ; eg. `refs/tags/v1.0.0`
+* `pr` ; eg. `refs/pull/318/merge`
+
+| Event           | Ref                           | Output                        |
+|-----------------|-------------------------------|-------------------------------|
+| `pull_request`  | `refs/pull/2/merge`           | `pr-2`                        |
+| `push`          | `refs/heads/master`           | `master`                      |
+| `push`          | `refs/heads/my/branch`        | `my-branch`                   |
+| `push tag`      | `refs/tags/v1.2.3`            | `v1.2.3`                      |
+| `push tag`      | `refs/tags/v2.0.8-beta.67`    | `v2.0.8-beta.67`              |
+
+Extended attributes and default values:
+
+```yaml
+tags: |
+  # branch event
+  type=ref,enable=true,priority=600,prefix=,suffix=,event=
+  # tag event
+  type=ref,enable=true,priority=600,prefix=,suffix=,event=
+  # pull request event
+  type=ref,enable=true,priority=600,prefix=pr-,suffix=,event=
+```
+
+### `type=raw`
+
+```yaml
+tags: |
+  type=raw,value=foo
+  type=raw,value=bar
+  # or
+  type=raw,foo
+  type=raw,bar
+  # or
+  foo
+  bar
+```
+
+Output custom tags according to your needs.
+
+Extended attributes and default values:
+
+```yaml
+tags: |
+  type=raw,enable=true,priority=200,prefix=,suffix=,value=
+```
+
+### `type=sha`
+
+```yaml
+tags: |
+  # minimal
+  type=sha
+```
+
+Output Git short commit as Docker tag like `sha-ad132f5`.
+
+Extended attributes and default values:
+
+```yaml
+tags: |
+  type=sha,enable=true,priority=100,prefix=sha-,suffix=
+```
+
+## Notes
+
+### Latest tag
+
+`latest` tag is handled through the [`flavor` input](#flavor-input). It will be generated by default (`auto` mode) for:
+* [`type=ref,event=tag`](#typeref)
+* [`type=semver,pattern=...`](#typesemver)
+* [`type=match,pattern=...`](#typematch)
+
+### Global expressions
+
+The following [Handlebars template](https://handlebarsjs.com/guide/) expressions for `prefix`, `suffix` and `value`
+attributes are available:
+
+| Expression               | Output               |
+|--------------------------|----------------------|
+| `{{branch}}`             | `master`             |
+| `{{tag}}`                | `v1.2.3`             |
+| `{{sha}}`                | `90dd603`            |
+
+```yaml
+tags: |
+  # dynamically set the branch name as a prefix
+  type=sha,prefix={{branch}}-
+  # dynamically set the branch name and sha as a custom tag
+  type=raw,value=mytag-{{branch}}-{{sha}}
+```
+
+### Major version zero
+
+Major version zero (`0.y.z`) is for initial development and **may** change at any time. This means the public API
+[**should not** be considered stable](https://semver.org/#spec-item-4).
+
+In this case, Docker tag `0` **should not** be generated if you're using [`type=semver`](#typesemver) with `{{major}}`
+pattern. You can manage this behavior like this:
+
+```yaml
+# refs/tags/v0.1.2
+tags: |
+  # output 0.1.2
+  type=semver,pattern={{version}}
+  # output 0.1
+  type=semver,pattern={{major}}.{{minor}}
+  # disabled if major zero
+  type=semver,pattern={{major}},enable=${{ !startsWith(github.ref, 'refs/tags/v0.') }}
+```
+
+### Overwrite labels
+
+If some of the [OCI Image Format Specification](https://github.com/opencontainers/image-spec/blob/master/annotations.md)
+labels generated are not suitable, you can overwrite them like this:
+
+```yaml
+      -
+        name: Docker meta
+        id: docker_meta
+        uses: crazy-max/ghaction-docker-meta@v2
+        with:
+          images: name/app
+          labels: |
+            maintainer=CrazyMax
+            org.opencontainers.image.title=MyCustomTitle
+            org.opencontainers.image.description=Another description
+            org.opencontainers.image.vendor=MyCompany
+```
