+# release-drafter automatically creates a draft release for you each time you complete a PR in the main branch.
+# It uses GitHub labels to categorize changes (See categories) and draft the release.
+# release-drafter also generates a version for your release based on GitHub labels. You can add a label of 'major',
+# 'minor' or 'patch' to determine which number in the version to increment.
+# You may need to add these labels yourself.
+# See https://github.com/release-drafter/release-drafter
