+Commit Message formatting
+-------------------------
+To ensure that all commit messages in the master branch follow a specific format, we
+enforce that all commit messages must follow the following format:
+
+.. code-block:: bash
+  FEAT-#9999: Add `DataFrame.rolling` functionality, to enable rolling window operations
+The ``FEAT`` component represents the type of commit. This component of the commit
+message can be one of the following:
+
+* FEAT: A new feature that is added
+* DOCS: Documentation improvements or updates
+* FIX: A bugfix contribution
+* REFACTOR: Moving or removing code without change in functionality
+* TEST: Test updates or improvements
+
+The ``#9999`` component of the commit message should be the issue number in the Modin
+GitHub issue tracker: https://github.com/modin-project/modin/issues. This is important
+because it links commits to their issues.
+
+The commit message should follow a colon (:) and be descriptive and succinct.
