A minor nitpick, but it would be great if you put a description of the site in the meta/og description[0] so people get an explanation of what the site is when linking elsewhere, e.g. the same "This page is a free and open-source wiki about hardware hacking!" as is on the page itself. I just linked the site in Slack and it just says "hardbreak.wiki / Welcome to HardBreak | Hardbreak" which is pretty terse. I imagine there might be some setting in your wiki software that might populate these tags automatically (moreso than they already have), with any luck!
