Installation help!!!

Would you be so kind as to write a manual for beginners, because not all specialists are in Linux. I do everything according to the manual, but one thing does not work, then something else, and not everything is clear. When I installed Ranked-stats from niekcandaele. that everything turned out in 15 minutes, everything is clear and understandable there.
The sequence of actions itself is unclear.

Just FYI the wiki has some information about the database stuff here https://github.com/PhlexPlexico/G5API/wiki/Configuration#apply-database-configs

As for the yarn install it shouldn't need install or the --production flag I believe? yarn should just install all the packages.
