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.
There's a zillion self-hosted wiki solutions out there and you might be wondering why I settled on Wiki.js. To keep it short: looks nice, is actively developed, and is widely used.
Yes, v2 isn't fully complete yet, but progress is coming along nicely.
Again, to keep it short: looks ugly, I've had issues with the search indexing, the non-standard Markdown is awful, and I hate strongly dislike PHP.
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.
