Coding

I really want to get into coding for ArmA 3 and begin to make my own scripts, menus, and my own unique content for in game. I am just stuck at where I should start. Is there anywhere that you could recommend me to start, if so please leave me some useful links down below. I usually learn best from watching videos but if all you have is text then please do comment with the links and other content that could help me.

Thanks in advance

Google!

Do what I did and go download released menus and study them
