I want to learn how to create plugins and the only place where I can do this is uMod. But I encountered a problem that made it difficult to study. I see hooks, but I don't understand how to use them or what you can do with them.
I decided to ask you for advice on how to make something out of the provided documentation?
How to use these hooks, and if you do not find it difficult to write everything that can help in my endeavor!
I will be grateful to everyone and I will be ready to accept every particle of knowledge from you!

Generally beginners will start by looking at the source code of existing plugins.  There are currently over a thousand plugins available for download of varying importance and complexity.
