# Radarr
Here you will find a collection of Radarr Guides we've made.
!!! info "Radarr is a movie collection manager for Usenet and BitTorrent users. It can monitor multiple RSS feeds for new movies and will interface with clients and indexers to grab, sort, and rename them. It can also be configured to automatically upgrade the quality of existing files in the library when a better quality format becomes available."

(Default/Stable): It has been tested by users on the develop and nightly branches and it’s not known to have any major issues. This version will receive updates approximately monthly. On GitHub, this is the `master` branch.
(Beta): This is the testing edge. Released after being tested in the nightly branch to ensure no immediate issues. New features and bug fixes are released here first after nightly. It can be considered semi-stable but is still `beta`. This version will receive updates either weekly or biweekly depending on development.
!!! warning "**Warning: You may not be able to go back to `master` after switching to this branch.** On GitHub, this is a snapshot of the `develop` branch at a specific point in time."
(Alpha/Unstable) : This is the bleeding edge. It is released as soon as the code is committed and passes all automated tests. This build may have not been used by us or other users yet. There is no guarantee that it will even run in some cases. This branch is only recommended for advanced users. Issues and self-investigation are expected in this branch.
**_Use this branch only if you know what you are doing and are willing to get your hands dirty to recover a failed update._**
This version is updated immediately.
