## Lineage & Attribution

Chaptarr is a fork of [Readarr](https://github.com/Readarr/Readarr), an eBook and
audiobook manager that is part of the [Servarr](https://wiki.servarr.com/) project
family. Readarr is built on the shared codebase behind
[Sonarr](https://github.com/Sonarr/Sonarr),
[Radarr](https://github.com/Radarr/Radarr),
[Lidarr](https://github.com/Lidarr/Lidarr), and
[Prowlarr](https://github.com/Prowlarr/Prowlarr).

Chaptarr would not exist without the years of work the Servarr team and their
contributors put into those projects. We are grateful for it.
