This is a book (like thing) that I have been working on for a bit, It is unfinished (68k of 90-ish projected {first draft}). I'm ready to share it to get some feedback, and contributors (the code could absolutely use some massaging from someone with more experience than I).
More info can be found at the GitHub repo (which you can build from source if the website goes down), https://github.com/altruios/namshubettulpa
Have a wonderful day!
