@@ -216,7 +216,8 @@ If both ``prefix`` and ``from_pattern``/``to_pattern`` are used,
 ``from_pattern``/``to_pattern`` are ignored. If you want to strip the prefix
 and then do something special, just use ``from_pattern```/``to_pattern``. For
 example, the transformation of ``v1_1_0`` => ``1.1.0`` can be achieved with
-``from_pattern = v(\d+)_(\d+)_(\d+)`` and ``to_pattern = \1.\2.\3``.
+``from_pattern = 'v(\d+)_(\d+)_(\d+)'`` and ``to_pattern = '\1.\2.\3'``.
+(Note that in TOML it's easiler to write regexes in single quotes so you don't need to escape ``\\``.)
