+name: "Create PR custom action"
+description: "Create a PR and a temporary branch, close duplicates"
+
+# PROCESS
+#
+# 1. Setup git client using Powertools for AWS Lambda bot username
+# 2. Pushes staged files to a temporary branch
+# 3. Creates a PR from temporary branch against a target branch (typically trunk: develop, main, etc.)
+# 4. Searches for duplicate PRs with the same title
+# 5. If duplicates are found, link to the most recent one, close and delete their branches so we keep a single PR
+# 6. In the event of failure, we delete the now orphaned branch (if any), and propagate the failure
+
+# REQUIREMENTS
+# You need to enable "Allow GitHub Actions to create and approve pull requests" in your repository settings
+# You need to have "skip-changelog" label in your repository to skip changelog generation.
+
+# USAGE
