Just finished submitting it to libgen, I think it needs to be accepted first before it's available publicly but for now I think you can download it from ~~here~~? If the download link on this page is no good let me know and I'll try uploading it somewhere else.
Edit: OK nevermind on that link, I just realized that page is password protected well here's a link that should actually be visible to anyone while we wait for the libgen submission. https://gofile.io/d/OdIZlc
I’ve never really thought about it outside of the context of code, but I wonder if Git would be handy for this. Plain text and markdown would work perfectly, but there might be better version control systems for things like Office/LibreOffice.
