 ## Using with Second Life Viewer
 
+Connecting to the Second Life Viewer is the primary purpose of this plugin. Connecting does 2 things:
+1. Syncs scripts/notecards between VS Code and Second Life Viewer
+2. Downloads SLua language definition files from Second Life Viewer.

 ### Connection Setup
 
 1. **Enable External Script Editor** in Second Life viewer preferences
 2. **Set the editor** to connect via WebSocket on port 9020 (configurable)
