This topic would be incomplete without mentioning "bropages" => "Example-focused snippets"

eg: http://bropages.org/diff

...you need "man" pages for moderately-comprehensive options explanations (backed by /usr/share/doc/$TOOL/README.txt if you're a debian user), but "bro" tends to focus on the "yo, this is what you're actually trying to do here...", including sometimes crossing traditional "this-command" boundaries (eg: in the diff example, offering `diff <( cmd1 ) <( cmd2 )` b/c sometimes that's what people are trying to do).

I can't find one that I submitted but it was something like `bro sed` => `# bro, just use awk! => awk -- '{...}'` ...basically you could go down the wrong rabbit hole, and there's kindof a nice little community of users helping to lift each other up (with upvote/downvote) and focusing on providing relatively simple and salient examples rather than a wall-of-text-options where you know that it's possible, but you don't know how to start. (eg: see `bro ffmpeg`)
