+## Running 
+UCM desktop requires the UCM CLI to be running on a specific port and with a
+specific UCM token
+```bash
+UCM_TOKEN=asdf UCM_PORT=4444 ucm headless --allow-cors-host tauri://localhost
+```
+
+If on windows, use this command instead:
+```bash
+UCM_TOKEN=asdf UCM_PORT=4444 ucm headless --allow-cors-host http://tauri.localhost
+```
+
+Then start the UCM Desktop app as you would normally.
+
+## Running for development
+When running for development start UCM like so:
+
+```bash
+UCM_TOKEN=asdf UCM_PORT=4444 ucm headless --allow-cors-host http://localhost:1420
+```
+
+Then start the app with:
+
+```bash
+npm start
+```
