+Open **Settings** to confirm the MeTube URL, then add channels from the **Channels** view.

+> **If MeTube is also running in Docker on the same machine**, containers can't reach each other via `localhost`. Either place both on a shared network:
+> ```bash
+> docker network create media
+> docker run -d --name tubechecker --network media -p 8083:8083 \
+>   -v tubechecker-data:/data \
+>   -e METUBE_URL=http://metube:8081 \
+>   ghcr.io/spaggel/tubechecker:latest

+> Or use `host.docker.internal` as the hostname (Mac/Windows only; Linux typically uses `172.17.0.1`).
