Hey mate, so I just threw together 2 “Quick start” guides to set up a PM3 with you in mind.
Amal’s is very thorough with a lot of info, even if your first language was English, it is a lot to take in.
So I “dumbed” his down, and I made 2 versions
This one is a Step by step without the background info or explanations as to what and why you are doing it ( I think this might be a good one for you to try )
I wrote it as I did a clean build myself , so if you are on Windows 10 
you should be able to follow it step by Step

I did another that basically has just the commands, so super simple ( IF everything works as it should )
I would be keen to hear your thoughts if you try it
Good luck
Of course, if you get stuck, just ask…
