[Help!] How to make a mod for Garry's mod?

1. Have a clear idea of what you want to make. So you dont get lost or confused while doing it.
2. Get addons that have something you can use, you dont want to start from 0 to 1000 lines of code, maybe the mod you want to make could be done editing some stuff from another.
3. Adapt the other addon's code to your like, start changing simple stuff, then deleting, then merging other codes until you get what you want.
Note: Put a print() or darkrp.notify everywhere, so you know it works, then you can remove it. You can also do this on addons you don't understand
