+This rule raises an issue when ``++copy.replace++`` is used on an incorrect type.
+
 == Why is this an issue?
 
-Calling ``++copy.replace(...)++`` with an argument of an unsupported type will raise an ``++TypeError++``.
-Types supported by ``++copy.replace(...)++`` must implement the {object_replacement_protocol}[replace protocol]. 
+Python provides the function ``++copy.replace(obj, /, **changes)++`` which creates a new duplicate of the same type as ``++obj++`` then updating the values of the fields provided in ``++changes++``.
+However, calling ``++copy.replace(...)++`` with an argument of an unsupported type will raise an ``++TypeError++``.
+In order for a type to be supported by ``++copy.replace(...)++``, the {object_replacement_protocol}[replace protocol] must be implemented.
 
-The following built-in types are supported by ``++copy.replace(...)++``
+The following built-in types implement the {object_replacement_protocol}[replace protocol] and are thus supported by ``++copy.replace(...)++``
 
-* ``++collections.namedtuple()++``
-* ``++dataclasses.dataclass++``
 * ``++datetime.datetime++``, ``++datetime.date++``, ``++datetime.time++``
 * ``++inspect.Signature++``, ``++inspect.Parameter++``
 * ``++types.SimpleNamespace++``

 == How to fix it
 
-If the argument passed in is a class defined in this project then implementing the {object_replacement_protocol}[replace protocol] by defining the ``++__replace__++`` method. 
+If the argument passed to ``++copy.replace(...)++`` is a class defined in this project then, to fix the issue, implement the {object_replacement_protocol}[replace protocol] by defining the ``++__replace__++`` method in the class.
