+<!-- TODO: outline your action here -->
+This is a template repository for

+automation based on [action composition](https://docs.github.com/en/actions/creating-actions/creating-a-composite-action).
+Click `Use this template` button to create your reviewdog action :dog:!
+
+If you want to create your own reviewdog action from scratch without using this
+template, please check and copy release automation flow.
+It's important to manage release workflow and sync reviewdog version for all
+reviewdog actions.
+
+This repo contains a sample action to run [misspell](https://github.com/client9/misspell).

+## Development
+
+### Release
+
+#### [haya14busa/action-bumpr](https://github.com/haya14busa/action-bumpr)
+You can bump version on merging Pull Requests with specific labels (bump:major,bump:minor,bump:patch).
+Pushing tag manually by yourself also work.
+
+#### [haya14busa/action-update-semver](https://github.com/haya14busa/action-update-semver)
+
+This action updates major/minor release tags on a tag push. e.g. Update v1 and v1.2 tag when released v1.2.3.
+ref: https://help.github.com/en/articles/about-actions#versioning-your-action
+
+### Lint - reviewdog integration
+
+This reviewdog action itself is integrated with reviewdog to run lints
+which is useful for [action composition] based actions.
+
+[action composition]:https://docs.github.com/en/actions/creating-actions/creating-a-composite-action
