 # action-release
-A GitHub Action to release tags
+
+A GitHub Action to release tags.
+This is a composite action that combines other actions, like:
+
+- metcalfc/changelog-generator
+- softprops/action-gh-release
+- peter-evans/find-comment
+- chuhlomin/render-template
+- peter-evans/create-or-update-comment
+
+This action is mean to execute when new git tags are pushed (see how to create tags
+with [action-git-tag](https://github.com/GRESB/action-git-tag)).
+When invoked this action will create a change log, and a release (including the change log and user supplied input).
+If a PR number has been supplied it will look for a comment in that PR that contains a tag comment header.
+If the PR comment is found it will be updated, otherwise a new one is created with information about the release.
+
+## Inputs
+
+| Input              | Description                                                                                 | Required | Default                                                                               |

+| tag-comment-header | The header on the PR tag comment, used to update the comment and to find existing comments. | false    | '## Tag created'                                                                      |
+| body               | The text to post on the release.                                                            | true     |                                                                                       |

+
+## Usage
+
+The default `secrets.GITHUB_TOKEN` is able to create the release and comment on the pull request.
+
+To create pull request comments, the action needs a template under `.github/templates/tag-comment.md`, with the
+following variables.
+
+```md
+{{ .header }}
+
+Tag: `{{ .tag }}`
+
+{{ .body }}
+
+{{ .footer }}
+```
+
+The template can contain any other static text.
+
