Bluebird

I am making a pirating server and I am following this guide and I got to the part where I need to choose indexers in Jackett.

What is an indexer exactly? I noticed that some are public and some are private. Are private indexers paid?

I do not know which ones to choose so any help would be appreciated.

I am trying to set up my own server for movies/tv with all the bells and whistles to make it the most streaming service like where I can browse and have automatically torrented and downloaded for viewing. I am new to all of it so a guide would be really helpful.

I came across this guide but it is 2 years old and while it most definitely would still be fine I wanted to know if there is anything more current.

I will be using this mini pc to host the server and probably some other things like a lemmy instance.
