+### Conventional Commits (semver with smarts) 💡
+
+If you choose the conventional commits scheme, the action will parse the last commit message _(usually the merge commit)_ to determine
+the increment type for a `semver` version.
+
+The following increment types by keyword are supported:
+ - patch: build, chore, ci, docs, fix, perf, refactor, revert, style, test
+ - minor: feat
+ - major: any of the above keywords followed by a '!' character, or 'BREAKING CHANGE:' in commit body
+
+If none of the keywords are detected, then the increment specified by the `increment` input will be used (defaults to patch).
+
+> [!TIP]
+> You might like to _enforce_ conventional commits in the title of your pull requests to ensure that the merge commit has the correct
+> information.  Something like this action might be handy: https://github.com/marketplace/actions/conventional-commit-in-pull-requests
