-# Summary
-# -------
-# This tutorial provides a walk through of TVM workflow using
-# a vector add example. The general workflow is
+################################################################################
+# .. note:: Code Specialization
+#
+# As you may have noticed, the declarations of A, B and C all take the same
+# shape argument, n. TVM will take advantage of this to pass only a single
+# shape argument to the kernel, as you will find in the printed device code.
+# This is one form of specialization.
+#
+# On the host side, TVM will automatically generate check code that checks
+# the constraints in the parameters. So if you pass arrays with different
+# shapes into fadd, an error will be raised.
+#
+# We can do more specializations. For example, we can write :code:`n =
+# tvm.runtime.convert(1024)` instead of :code:`n = te.var("n")`, in the
+# computation declaration. The generated function will only take vectors with
+# length 1024.
+
+################################################################################
+# .. note:: TE Scheduling Primitives
+#
+# TVM includes a number of different scheduling primitives:
+#
+# - split: splits a specified axis into two axises by the defined factor.
+# - tile: tiles will split a computation across two axes by the defined
factors.
+# - fuse: fuses two consecutive axises of one computation.
+# - reorder: can reorder the axises of a computation into a defined order.
+# - bind: can bind a computation to a specific thread, useful in GPU
programming.
+# - compute_at: by default, TVM will compute tensors at the root by default.

Review comment:
I think it means at the root of the computation graph?
