Every homepage for a BitTorrent client shows using it to download a Linux .iso (GPL) or the short film Big Buck Bunny (Creative Commons).
Maybe make the examples in your guide legal but the steps can be the same as for illegal, e.g. "Here's how you can use The Pirate Bay & QBittorrent to find & download Big.Buck.Bunny.1080p.mp4".
Then, when they follow the steps in your guide, they can change Big Buck Bunny to whatever they want to download.
