I think it is worth pointing out to those that don’t know that automation via the *arr apps is optional. Sure, it’s great, but it’s not like you need to learn that whole toolchain right away. With a good indexer, a good server, and a good download app you can get going really easily. You’re just doing manual searches and clicking to download nzb files.
I have also found that having more than one indexer helps. Part of the trick is finding a few that complement each other–and then getting an invitation to register. Everyone has their own opinion on what combos are good.
