I recommend switching to Myrient! Has been my source for quite some time now, because Vimms was just to slow for me.

I am very new to the whole torrenting and stremio thing, so I have basically no clue how to utilise any new indexers. I just looked up what it actually means and as far as I understand, they are the tools to find suitable torrents for the target media, is that right? So, is the goal here is to replace Torrentio and hook it up to stremio by itself?

Because the setup has to be cheap and secure, I will probably have to rely on RD and I am not aware of any way to use its service outside of Torrentio.

Or does switching to the *arr alternatives provide enough security while living in Germany. I am really not looking forward to getting annoying letters for any leaking.
