Offtopic, but I noticed that this website uses the SF Mono font on their code blocks, is that fine? And no, I don't work for Apple (or anytone, for that matter), I just checked because I'm searching for a (preferably FOSS) free font that looks like SF Mono.

I think SF Mono is the best as well. The closest fonts to it that I know of are Commit Mono, Source Code Pro and Consolas.
