Add custom .mdl to my addons

Hi,
I’m currently learning lua and modelling prop with blender for gmod.
I just achieve my first prop which is a prop of a door, I can spawn it in solo everything is ok but I just want to know how to add it to my addons folder to use it or spawn it with my code, and also make it downloadable.
I have these files


I don’t even know how structure my addons folder to add it and if i had to add everythings or only the .MDL
Thanks in advance !
