What is Sonarr?
Sonarr is a PVR (personal video recorder) for Usenet and BitTorrent users. It automatically monitors multiple RSS feeds and indexers for new and upgraded episodes of your wanted TV series, grabs them through your download client, then renames and organizes them into your library by series, season, and episode. Think of it as the TV-focused sibling of Radarr — part of the broader *arr stack alongside Prowlarr, Radarr, and Bazarr.
Sonarr handles quality profiles, custom formats, automatic upgrades (e.g. replacing a 720p episode when a 1080p release appears), season pass monitoring, and release calendar tracking so it can grab new episodes the moment they air.
Sonarr pairs best with Prowlarr (indexer management) and a download client such as qBittorrent or SABnzbd. Set those up first for the smoothest experience.

/media/tv. - Under Settings → Profiles, configure quality profiles to match your storage and bandwidth.
