Need Help with layeredfs

I have been trying to get layeredfs working but I’m have problems. I have all the files in the right places but the mods don’t load. When I try and load a game with mods it crashes unless I hold down the L button. I been searching and reading some threads on here and I think I may have found the one problem. I am missing the override_config.ini file in the atmosphere/config folder. The folder is empty. Can someone tell me how to get the file.

I am on atmosphere 17.1 and firmware 10.2

 

Ok thanks I have got some mods working by installing simple mod manager. But I have another question. I see a lot of threading talking about how to install mods but you know of a tutorial that tells how to create mods?

 

Ok thanks I was just trying to edit some textures
