 class Rotating(Animation):
+    """Animation that rotates a Mobject.
+
+    Parameters
+    ----------
+    mobject
+        The mobject to be rotated.
+    angle
+        The rotation angle in radians. Predefined constants such as ``DEGREES``
+        can also be used to specify the angle in degrees.
+    axis
+        The rotation axis as a numpy vector.
+    about_point
+        The rotation center.
+    about_edge
+        If ``about_point`` is ``None``, this argument specifies
+        the direction of the bounding box point to be taken as
+        the rotation center.
+    run_time
+        The duration of the animation in seconds.
+    rate_func
+        The function defining the animation progress based on the relative
+        runtime (see :mod:`~.rate_functions`) .
+    **kwargs
+        Additional keyword arguments passed to :class:`~.Animation`.
