+
+.. decorator:: override
+
+   A decorator for methods that indicates to type checkers that this method
+   should override a method or attribute with the same name on a base class.
+   This helps prevent bugs that may occur when a base class is changed without
+   an equivalent change to a child class.
+
+   For example::
+
+      class Base:
+           def log_status(self)
+
+      class Sub(Base):
+          @override
+          def log_status(self) -> None:  # Okay: overrides Base.log_status
+              ...
+
+          @override
+          def done(self) -> None:  # Error reported by type checker
+              ...
+
+   There is no runtime checking of this property.
+
+   The decorator will set the ``__override__`` attribute to ``True`` on
+   the decorated object. Thus, a check like
+   ``if getattr(obj, "__override__", False)`` can be used at runtime to determine
+   whether an object ``obj`` has been marked as an override.  If the decorated object
+   does not support setting attributes, the decorator returns the object unchanged
+   without raising an exception.
+
+   See :pep:`698` for more details.

    Decorator to mark a class or function to be unavailable at runtime.
