I did a quick search and didn’t see anything on this. Basically it’s a free php script that makes your own private URL shortener so you don’t have to rely on 3rd party services and get screwed in the long run. It works pretty good and has done wonders for me. I would suggest purchasing a short domain and installing it on the short domain, or else whats the points of installing it in the subdomain of a large domain(the link still gonna be big lol)?
