Yea i did read first chapters but i feel like there are not all informacion in it, more leke some basic things. Meaby am wrong.

Also the problem is this book is for mods in minetest game, and since i want to make mods for Voxe Libre this book doesnt realy teach me that. Althou it helps understending how things related to engine works.

Haha thats funy but better let them grow up a bit and than explain what open source is, and let them chose open source way themselfs.
