+# D-Star Site - MMDVMHost Split Controller
+
+MMDVMHost with D-Star split controller Name= registration support.
+Connects Raspberry Pi 3 sites to cloud DStarRepeater split controller.
+
+## What this does
+
+Patches MMDVMHost to send a NETWORK_REGISTER packet with a site name
+to the DStarRepeater split controller, allowing the controller to
+identify each site by name rather than IP address only.
+
+## Sites
+
+| Site  | Name  | Gateway Port | Local Port | Description        |
+|-------|-------|-------------|------------|---------------------|
+| ORNG  | ORNG  | 20013       | 20016      | Orange Portable     |
+| ORNG2 | ORNG2 | 20013       | 20017      | Orange TXRX         |

+## Adding a New Site
+
+1. Create `sites/NEWSITE/site.conf` from existing template
+2. Add TXName/RXName to cloud DStarRepeater split config
+3. Run `sudo bash install.sh` on new Pi and select site
