 ## Overview
 - This is a Phoenix LiveView application for APRS (Automatic Packet Reporting System)
 - APRS is a digital communications system used by amateur radio operators
-- The app appears to track and display APRS packets/messages
+- The app tracks and displays APRS packets/messages in real-time on an interactive map
 
 ## Project Structure
 - Standard Phoenix 1.7+ structure with LiveView
@@ -14,15 +14,37 @@
 - Database with PostGIS for geographic data
 - Real-time features with PubSub and presence
 
-## Key Components Found
-- Map visualization (Leaflet integration)
-- Packet display and filtering
-- User authentication
-- Real-time updates
-- Weather data support
-- Geographic/spatial queries
+## Key Features Found
+- **Interactive Map**: Leaflet-based map with OpenStreetMap tiles
+- **Real-time APRS Tracking**: Connected to APRS-IS (dallas.aprs2.net:14580)
+- **Responsive Design**: Slideover panel for controls, mobile-friendly
+- **Search Functionality**: Callsign search capability
+- **Trail Display**: Configurable trail duration (1 hour to 1 week)
+- **Historical Data**: Historical packet loading (1-24 hours)
+- **Packet Display**: Multiple views (map, packets, status, weather, bad packets)
+- **User Authentication**: Complete auth system ready
+- **API Endpoints**: RESTful API for callsign data
+
+## Technical Stack
+- **Backend**: Phoenix 1.7, Elixir 1.17, Ecto with PostgreSQL + PostGIS
+- **Frontend**: LiveView, Tailwind CSS, Leaflet.js for maps
+- **Real-time**: Phoenix PubSub, WebSocket connections
+- **Background Jobs**: Oban for job processing
+- **External Integration**: APRS-IS network connection
+- **Deployment**: Docker-ready with releases
+
+## Current Status
+- ✅ Application runs successfully on localhost:4000
+- ✅ Database migrations completed
+- ✅ APRS-IS connection established
+- ✅ Map interface working with controls
+- ✅ Real-time packet processing active
+- ⚠️  Some asset loading optimizations possible
+- 📡 Currently showing "no internet" (likely due to APRS data feed)
 
 ## Next Steps
-- Check if deps are installed
-- Explore the database setup
-- Start the server to see the current state
+- Explore specific LiveView modules
+- Check packet data flow
+- Review real-time update mechanisms
+- Examine API capabilities
