+## 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 the Git tag matches a regular expression with the [`tag-match` input](#tag-match-examples) or if
+`tag-semver` is valid [semver](https://semver.org/).

+### Handle semver tag
+
+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:
+
+| Git tag            | `tag-semver`                                             | Valid              | Output tags                | Output version               |
+|--------------------|----------------------------------------------------------|--------------------|----------------------------|------------------------------|
+| `v1.2.3`           | `{{raw}}`                                                | :white_check_mark: | `v1.2.3`, `latest`         | `v1.2.3`                     |
+| `v1.2.3`           | `{{version}}`                                            | :white_check_mark: | `1.2.3`, `latest`          | `1.2.3`                      |
+| `v1.2.3`           | `{{major}}.{{minor}}`                                    | :white_check_mark: | `1.2`, `latest`            | `1.2`                        |

+| `v1.2.3`           | `{{minor}}`                                              | :white_check_mark: | `2`, `latest`              | `2`                          |

+| `v1.2.3`           | `{{major}}.{{minor}}`<br>`{{major}}.{{minor}}.{{patch}}` | :white_check_mark: | `1.2`, `1.2.3`, `latest`   | `1.2`*                       |

+| `v2.0.8-beta.67`   | `{{major}}.{{minor}}`                                    | :white_check_mark: | `2.0.8-beta.67`**          | `2.0.8-beta.67`              |
+| `release1`         | `{{raw}}`                                                | :x:                | `release1`                 | `release1`                   |
+
+> *First occurrence of `tag-semver` will be taken as `output.version`
+
+> **Pre-release (rc, beta, alpha) will only extend `{{version}}` as tag
+
+### 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).
+
+### 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: Build and push
+        uses: docker/build-push-action@v2
+        with:
+          context: .
+          file: ./Dockerfile
+          platforms: linux/amd64,linux/arm64,linux/386
+          push: ${{ github.event_name != 'pull_request' }}
+          tags: ${{ steps.docker_meta.outputs.tags }}
+          labels: |
+            ${{ steps.docker_meta.outputs.labels }}
+            org.opencontainers.image.title=MyCustomTitle
+            org.opencontainers.image.description=Another description
+            org.opencontainers.image.vendor=MyCompany
