+# CHIP TV Casting App Example
+
+This is a CHIP TV Casting app that can be used to cast content to a TV. This app
+discovers TVs on the local network that act as commissioners, lets the user
+select one, sends the TV a User Directed Commissioning request, enters
+commisioning mode, advertises itself as a Commissionable Node and gets
+commissioned. Then it allows the user to send CHIP ContentLauncher commands to
+the TV.
