+## Configuration Details
+
+### Load Balancing
+
+**MAX_CAPACITY** (integer, default: 1000)
+- Soft capacity limit for the server
+- When reached, the load balancer will prioritize other servers
+- Does not prevent new connections, just influences routing decisions
+- Range: 1-32,767 (int2)
+- Used by the Supabase Edge Function `connection-request` for optimal server selection
+
+### Server Registration
+
+**SERVER_ID** (string, required)
+- Unique identifier for the server in the Waylume network
+- Used for rolling codes authentication and session tracking
+- Should be URL-safe (alphanumeric with hyphens/underscores)
+
+**Geographic Information** (optional but recommended)
+- Enables location-based server selection for premium users
+- Improves load distribution across regions
+- Required for the location selection feature in the client app
+
 ## Quick Deployment
