[MODS] NearInfinity Tutorial for BGII:EE Available?

Hello and good day.
Although i visit the forum a lot, i have never created an account until now.
After installing some mods I decided that as a programer I could do one my self. With some research on the forum I discovered that I needed Near Infinity software. I downloaded it and got it running. Did some researches and I did not find exacly how to start and how to publish them with WeiDU. I wanted at first to develop a class kit, a simple one. Could any provide some information? Links? The content I have found on the web did not help much, nor the videos on YouTube.
