## Introduction
Radarr is a movie download automation tool that ties together your movie collection, indexers, trackers as well as your usenet and torrent download client. It supports a wide variety of newznab usenet indexers, a number of torrent trackers, a handful of usenet download clients and a couple handfuls of torrent download clients. You can greatly expand the number of supported torrent trackers with [jackett](https://github.com/Jackett/Jackett/releases), a tracker to torznab proxy.
## How Radarr Works
One of the most misunderstood mechanisms of Radarr is how it finds movies to add to your collection. It seems obvious to most new users, it searches for them. And if it isn't found then, it'll search later for them. Right? But this is not how it works. If you think about it, that sort of mechanism does not scale at all. If you search every day and have 10 missing movies, that is 10 searches. If you have 100 missing movies, that is 100 searches. If you have 1000 missing movies, 1000 searches. Every day.
Instead, Radarr does an "RSS" sync every 15-60 minutes which queries your indexers and trackers for newly posted content. *Most* of the time, this means new releases... but with usenet, where reposts are more common, this can be older content. It isn't as common with torrents, but it does happen occasionally. So a movie added to Radarr may never download if it never shows up as newly posted content on your tracker or indexer. So how can this be feasible?
Instead, Radarr does an "RSS" sync every 15-60 minutes which queries your indexers and trackers for newly posted content which lets Radarr cover *any number* of needed movies with just 24-96 queries per day. Your library size, number of movies that are missing or need upgrade no longer matter. *Most* of these "RSS" queries return new content... but with usenet, where reposts are more common, older content is fairly common, but it isn't as common with torrents. So a movie added to Radarr may never download if it never shows up as newly posted content on your tracker or indexer. So how can this be feasible?
When you're adding a movie you know can already be downloaded, you'll pick the right profile, root folder and monitor status... you'll check the "Start search for missing movie" box and then add the movie. This will add the movie and initiate a search, which covers the past and the present. That let's "RSS" cover the future.

And the best part of "RSS" is that it is *actually* a search, but without any query parameters besides your indexer/tracker categories.
## Indexers and Trackers
You will need to get your `.nzb` files from a usenet indexer and/or `.torrent` files from a torrent tracker. There are many public and private, well known and secret options available and I suggest [/r/usenet](https://reddit.com/r/usenet/) and [/r/torrents](https://reddit.com/r/torrents/) as good starting points for finding them.
But how do you decide, torrents or usenet? Personally, I'd suggest *both*. But if you want to go one way or the other, that is fine too. Torrents have the benefit of being very inexpensive, where the only real cost is a VPN to keep you safe. On the other hand, you'll pay a small amount for a few good usenet indexers and a bigger amount for a usenet provider or two... but you won't have to seed. On the gripping hand, having both setup means you get all the benefits of both.
## Download Client
You'll need to pick a download client.
For usenet, this is very easy because [nzbget](https://nzbget.net/) and [sabnzbd](https://sabnzbd.org/) are pretty much the only reasonable options and they're *both* fantastic. Pick one or the other based on looking at their sites and if you like it, you're done. If you don't like it, try the other one. There are *tiny* differences between them, but they're both wonderful and you can't go wrong either way.
But now we come to torrent clients, and my opinion of them is that there are none that are as good as the above usenet download clients. I would start with [qBittorrent](https://www.qbittorrent.org/) which has been growing in popularity and seems to be actively developed. If that doesn't suit, I would try [Deluge](https://deluge-torrent.org/) next. Finally, as an [rTorrent](https://github.com/rakshasa/rtorrent) user myself... I would try it last. And you should absolutely scour the internet for articles, opinions and comments about each one because they are *all* very different and some do certain things a *lot* better than others. And don't forget, *extraction* of packed torrents is an after thought in all of them.
