Hello slicer community

First of all I’m a noob in slicer dev.

1. I started searching for documentations about development of slicer modules.  
2 . I built my own module and try to understand the code… but here i’m now stuck , It’s very confusing to me. (import, qt design ui …)
2. My goal is to do a simple module with buttons that launch some “logic()” of the “segment editor” module. (threshold, islands)

And with all my reading i have no clue of how to do it ;(

edit: Slicer 4.11.202000930  
Do you have some informations documentations that can be useful to me ?

Thank you all.
