System plugin tutorial

Hello there!

I write a small tutorial for the system plugin.

Hope it helps people 😉

Here.

Found my old post 😁

Anyway, before uploading...what you thing about it?

Thanks to: kichik, Anders, deguix, dor <- 😛 and other people that direct or indirect help me a lot.... I must say... this isn't a 100% work of mine... thanks to all 👍

Hey Hey! Thanks Joelito!👍

I found this VERY useful, as an initial look at the official docs made me think "look at this stuff later".

This made me see that its not going to be as difficult to fathom as I first thought.

Thanks Arrby 😁

I like the words look at this stuff later. 👍

Ok... uploaded and ready to serve. 🙂
