You can't find guides yet because modding is not officially supported so things have changed often, apparently (don't know, I started after patch9...).

First things to do is to extract the game's .pak files with this tool : https://github.com/Norbyte/lslib

This tool also allow you to extract existing mod's .pak files.
This os very usefull to understand what you're reading.
