+Ignoring commits with git blame.ignoreRevsFile
+==============================================
+
+As of git 2.23, it is possible to make formatting changes without breaking
+``git blame``. See the `git documentation
+`_
+for more details.
+
+To use this feature you must:
+
+- Install git >= 2.23
+- Configure your local git repo by running:
+ - POSIX: ``tools\configure-git-blame-ignore-revs.sh``
+ - Windows: ``tools\configure-git-blame-ignore-revs.bat``
