To be clear, this is just a joke, and I don't look down on direct downloading. It absolutely has its place, and sometimes I do it myself if it's just faster to download a file directly. Torrenting is just so much more convenient, though, especially when using Jackett's manual search.
You probably have, but did you follow the official configuration tutorial?
I had no trouble setting it up before. Seemed very easy to me. Where are you getting stuck in the process?
Alternatively, you could just search directly in Jackett's interface with the "manual search" option. That's what I do. I find it preferable to setting it up with the Qbit search engine since Jackett's search has more features.
