Hi guys and girls

I just joined a game graphics eduction to become a game dev and i have some basic blender knowledge.
I wanted to expand my knowledge and start modding. I want to start small and create an extra weapon but i don't know how to implement it into the game. I have no modding experience at all. Is there any place to get some tutorials on how to start or any discord that guides people?

Thanks allready
