Hey there!
Recently I've taken interest in developing a few mods of my own. Before you ask I'm very comfortable when it comes to C and thus C++ along with a handful of other languages. It would be very helpful if someone could link the resources/tools needed. Then possibly a brief description to getting started when developing GTA 5 mods nowadays.
Thank you for the help in advanced!

EDIT: I forgot to mention this post is geared towards the PC version.
