feat: add local connector domain stack

README.md

@@ -10,3 +10,17 @@ For production, place the service behind HTTPS and set `PUBLIC_BASE_URL` and
 `APPROVAL_BASE_URL` to its HTTPS address. Scanning the TV QR code opens a phone
 approval form protected by `PAIRING_SECRET`; replace that form with your own
 identity provider for a production connector.

+## Local OrbStack development
+
+Copy `.env.example` to `.env`, set `MEDIA_ROOT` to an absolute directory with
+video files, then start the shared-Caddy stack:
+
+```sh
+docker compose -p cleanstream-connector-local-domain -f docker-compose.local-domain.yml up -d
+```
+
+The connector is available at `https://cleanstream-connector.test`. The TV and
+phone must be on the same LAN. Because this uses Caddy's internal certificate,
+the phone must trust the local Caddy root certificate before it can open the QR
+approval URL.
