UPDATED VERSION: FULL TUTORIALS ON MOD INSTALLATION, FIXING ALL CRASHES, ETC.
This is the only guide ever devoted specifically to GTA V modding.
This colorful magazine briefly describes all the main aspects of modding, analyzes the structure of the game, gives definitions for terms and provides information about game files.
Attention! This encyclopedia is not an exclusive modding guide or tutorial. This book will not teach you how to make mods, but it can introduce you to the basics, for the most beginners. An experienced user, I think, can also get something useful for themselves.
More updates to come so stay tuned. Feedback, good or bad is welcome.
