 ## Virtual League
 
 The Virtual League is often the first chance you'll have to test your strategies
-against other teams. You'll [submit][code-submitter] your robot code for running
-against other teams in the [simulator][simulator]. The matches are livestreamed

+against other teams. The Virtual League plays the same game as the physical
+competition, though takes place in the [simulator][simulator]. You'll write
+code for a [simulated robot][simulated-robot] which both supports the same
+programming interface as your physical robot and has a wide array of sensors.
+
+This allows you to use the simulator and the Virtual League to learn about
+writing code for a robot as well as developing the code for your physical robot
+before it's fully built. The Virtual League is thus a both a first test of your
+code as well as an early opportunity to explore strategies for competing against
+other teams.

+Shortly before the event you'll [submit][code-submitter] your robot code so the
+matches can be simulated. The matches are then livestreamed on our
+[YouTube Channel][youtube]. Afterwards you'll get a copy of your simulated
+robot's logs so you can continue to improve your code.
