+## Third-Party Commitizen Templates
+
+In addition to the native templates, some alternative commit format templates
+are available as PyPI packages (installable with `pip`).
+
+### [Conventional JIRA](https://pypi.org/project/conventional-JIRA/)
+
+Just like *conventional commit* format, but the scope has been restricted to a
+JIRA issue format, i.e. `project-issueNumber`. This standardises scopes in a
+meaningful way.
+
+It can be installed with `pip install conventional-JIRA`.
