Modding Needs To Be Shared

So there are mods coming out left and right from people all the time, and i cant find anyway to learn how to make one myself! ive looked and i guess i just suck at looking but im not finding anything! i found the mcp56 but that doesnt work, if anyone with any experience modding could give me some help and maybe anyone else who reads this, i know id be much appreciative. thanks in advance! :D

also, feel free to comment all you like, maybe something you say will help me or another. :D
