+

+* `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

+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/)

+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:

+
+### `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: |
+  # 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`

+| `push tag`      | `refs/tags/v2.0.8-beta.67`    | `v2.0.8-beta.67`              |
+
+Extended attributes and default values:

+  # tag event
+  type=ref,enable=true,priority=600,prefix=,suffix=,event=

+```

+
+```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 Docker tag will be generated by default on `push tag` event. If for example you push the `v1.2.3` Git tag,
-you will have at the output of this action the Docker tags `v1.2.3` and `latest`. But you can allow the latest tag to be
-generated only if `tag-semver` is a valid [semver](https://semver.org/) or if Git tag matches a regular expression
-with the [`tag-match` input](#tag-match-examples). Can be disabled if `tag-latest` is `false`.
+`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)

-### Handle semver tag
+### Global expressions

-If Git tag is a valid [semver](https://semver.org/) you can handle it to output multi Docker tags at once.
-`tag-semver` supports multi-line [Handlebars template](https://handlebarsjs.com/guide/) with the following inputs:
+The following [Handlebars template](https://handlebarsjs.com/guide/) expressions for `prefix`, `suffix` and `value`
+attributes are available:

+  type=sha,prefix={{branch}}-
+  # dynamically set the branch name and sha as a custom tag
+  type=raw,value=mytag-{{branch}}-{{sha}}
+```

-> **Pre-release (rc, beta, alpha) will only extend `{{version}}` as tag because they are updated frequently,
-> and contain many breaking changes that are (by the author's design) not yet fit for public consumption.
+### Major version zero

-### `tag-match` examples
+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).

-| Git tag                 | `tag-match`                        | `tag-match-group` | Match                | Output tags               | Output version               |

-| `v2.0.8-beta.67`        | `v(.*)`                            | `1`               | :white_check_mark:   | `2.0.8-beta.67`, `latest` | `2.0.8-beta.67`              |
-| `v2.0.8-beta.67`        | `v(\d.\d)`                         | `1`               | :white_check_mark:   | `2.0`, `latest`           | `2.0`                        |
-| `release1`              | `\d{1,3}.\d{1,3}`                  | `0`               | :x:                  | `release1`                | `release1`                   |

+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:

-### Schedule tag
-
-`tag-schedule` is specially crafted input to support [Handlebars template](https://handlebarsjs.com/guide/) with
-the following expressions:
-
-| Expression              | Example                                   | Description                              |
-|-------------------------|-------------------------------------------|------------------------------------------|
-| `{{date 'format'}}`     | `{{date 'YYYYMMDD'}}` > `20200110`        | Render date by its [moment format](https://momentjs.com/docs/#/displaying/format/)
-
-You can find more examples in the [CI workflow](.github/workflows/ci.yml).
+```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.') }}
