Build rpcs3 from vlj

Have you followed simple builds instructions thoroughly?
You probably missing: "To initialize the repository don't forget to execute git submodule update --init"

You right, i don't get it. Where i have to paste it or how execute this command.

First, you should have git installed (I recommend https://desktop.github.com/ since it's easy to use)
Then, just clone the repo via it (you can just press clone in desktop button on repo page on github, or adding it manually through app with this clone url https://github.com/RPCS3/rpcs3.git).
when it will either clone it with submodules (don't remember if it did it automatically) or you'll have to open git shell (right click on the repo in gh desktop - open in git shell) and paste and execute this command in it

Code:

git submodule update --init
