Oh one of these has a title in spanish, nice. I think this is the first one in the repo like that (idk its been a while plus i didn't start this repo) so its no big deal and I'll merge this either way.

For future non-english PRs it might be worth looking into starting some translated copies of the main branch or just forking the repo that way the search-abilty of the files isn't impacted. It would be cool to have all of the file names translated into various languages tbh
