 ## 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`.
+
+### 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:
