 # Librarr
 
-Self-hosted book, audiobook, and manga search and download manager.
+**The missing *arr for books.** Self-hosted book, audiobook, and manga search and download manager — like Sonarr/Radarr but for your reading library.
 
-Librarr aggregates 13 search sources into a single interface, handles downloads via qBittorrent or SABnzbd, and automatically organizes files into your Calibre, Audiobookshelf, Kavita, or Komga libraries. It exposes a Torznab/Newznab API so it can act as an indexer in Prowlarr or Readarr, and an OPDS 1.2 feed for e-readers.
+Librarr searches 13 sources simultaneously, scores results by confidence, and auto-imports into your Calibre, Audiobookshelf, Kavita, or Komga library. Single 17MB Go binary. No runtime dependencies.
