   <h1>Edge TPU Performance Demo</h1>
-  <h2>Object detection and classification</h2>
-  <p>The following program demonstrates the processing power of the Edge TPU by
-  running MobileNet model that can concurrently identify and classify multiple
-  objects in a video. This demo is running a model with the MobileNet SSD v2
-  architecture, trained to detected 90 different object types from the COCO
-  dataset.
+  <p>The video below demonstrates the realtime processing power of the Edge TPU by
+    running a MobileNet SSD model that can identify and classify multiple objects.
+    The footage of the cars is a recording, but the MobileNet model is executing in
+    realtime on your Coral Dev Board to detect each car indicated with a box
+    (limited to 20 detected cars).</p>
+  <p>In the terminal where you started the demo, press the N key to switch between
+    running the model on either the Edge TPU or the CPU (quad-core Cortex-A53).</p>
