xnaasKB is simply a wiki I've created to track information and knowledge I've found over the years.
Prior to this, all of my "documentation" existed as bookmarks to archive.org or Reddit links, random text files and PDFs across various filesystems, a portable DokuWiki instance, a portable git repo, and more. I got fed up with the disorganization and ugliness of my non-solutions.
Yes, v2 isn't fully complete yet, but progress is coming along nicely.
Another popular wiki solution right now is BookStack and you might be wondering why I didn't go with that. I considered it for a moment, but my same dislike for PHP prevailed here. It does look pretty though.
I don't have much else for you other than to say "I hope some information here proves useful to you" and to provide you with a picture of my cat, Tux. She's a good bad kitty.
