+# Higher order gradient
+
+Some operators support higher order gradients. Meaning that you calculate the gradient of the
+gradient. For this the operator's backward must be as well differentiable. Some operators support
+differentiating multiple times, and others two, most just once.
+
+For calculating higher order gradients, we can use the `mx.autograd.grad` function while recording
+and then call backward, or call `mx.autograd.grad` two times. If we do the later is important that
 
 Review comment:
   later -> latter
