+        localns (dict | None): Dictionary containing local variables.
+
+        attribs (list | None):
+            List of attribs for the given class. This is necessary when calling
+            from inside a ``field_transformer`` since *cls* is not an *attrs*
+            class yet.
+
+        include_extras (bool):
+            Resolve more accurately, if possible. Pass ``include_extras`` to
+            ``typing.get_hints``, if supported by the typing module. On
+            supported Python versions (3.9+), this resolves the types more
+            accurately.
+
+    Raises:
+        TypeError: If *cls* is not a class.
+
+        attrs.exceptions.NotAnAttrsClassError:
+            If *cls* is not an *attrs* class and you didn't pass any attribs.
+
+        NameError: If types cannot be resolved because of missing variables.
+
+    Returns:
+        *cls* so you can use this function also as a class decorator. Please
+        note that you have to apply it **after** `attrs.define`. That means the
+        decorator has to come in the line **before** `attrs.define`.
