+## GitHub Workflow Examples
+GitHub Actions enable automating key parts of your development process.
+
+### Create Release Tag & Draft Release - By Workflow Dispatch
+This workflow automates the creation of a release tag and a draft release, triggered manually via a workflow dispatch.
+Tag is created after successful release notes generation to avoid manual removing of the tag if the release notes are not generated due to wrong configuration.
+
+See the [example of workflow](./examples/release_draft.yml).
+
+### Check Release Notes Presence - in Pull Request Description 
+This workflow checks that every pull request includes release notes in the description.
+- The check can be skipped by using the `skip-release-notes` label.
+- The check is searching a `[Rr]elease [Nn]otes:` strings in the PR description.
+
+See the [example of workflow](./examples/check_pr_release_notes.yml).
+
