+## Notes
+
+### Latest tag
+
+`latest` tag is created only on `push tag` event and resolves one of the following conditions:
+
+* Git tag is a valid [semver](https://semver.org/)
+* Provided `tag-coerce-tag` is valid
+
+### Coerces Git tag
+
+Provides a very forgiving translation of a non-semver tag to semver. For more information see
+[Coercion section](https://www.npmjs.com/package/semver#coercion). `tag-coerce-tag` supports
+[Handlebars template](https://handlebarsjs.com/guide/) with the following inputs:
+
+| `tag-coerce-tag`        | Git tag  | Version |
+|-------------------------|----------|---------|
+| `{{raw}}`               | `v1.2.3` | `1.2.3` |
+| `{{major}}.{{minor}}`   | `v1.2.3` | `1.2`   |
+| `{{major}}`             | `v1.2.3` | `1`     |
+| `{{minor}}`             | `v1.2.3` | `2`     |
+| `{{patch}}`             | `v1.2.3` | `3`     |
+
+### Templates available for 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/)
