First-install notes
- First login and third-party dependencies The default web-login password is 'raidisnotabackup'; change it after your first sign-in. Posterr depends on your Plex, Sonarr, Radarr, and Readarr instances, so keep those services running — some features will fail if they are unavailable or incompatible. source
