 ### Features
-(Not all of these features are fully implemented yet - see below)
+Not all of these features are fully implemented yet - see below.  But they should be in by the time we decide to call this project beta (three months?)
 
 * Very long battery life (should be about 8 days with the beta software)
 * Built in GPS and LORA radio, but we manage the radio automatically for you
 * Long range - a few miles per node but each node will forward packets as needed
 * Shows direction and distance to all members of your channel
+* Directed or broadcast text messages for channel members
 * Open and extensible codebase supporting multiple hardware vendors - no lock in to one vendor
-* Communication API for bluetooth devices (such as our Android app) to use the mesh
+* Communication API for bluetooth devices (such as our Android app) to use the mesh.  So if you have some application that needs long range low power networking, this might work for you.
 * Eventually (within a couple of months) we should have a modified version of Signal that works with this project.
+* Very easy sharing of private secured channels.  Just share a special link or QR code with other users and they can join your encrypted mesh
