Installing Overleaf (Sharelatex) without Docker (2024-07-30)

Tested on Debian 12.6 I started with another guide (https://gist.github.com/gelim/a840a99d15cb765cb7b65105b72f00c4), but quickly realized, I wanted to go another route (no runit for example)

Following this guide, it is possible to deploy Overleaf without Docker, but there are no guarantuees it will work nor is there any support for this method by the great folds of Overleaf. This procedure was tested by me on various machines and I did not find any problems with it, all services are running,
