.........i dont understand what do i have to put in there every .lua file or the folder
In the folder named 'Lua', that is where you will put menu.lua.
Also in the folder named 'Lua', that is where you will put the folder named 'menu'
The file named 'menu.lua' will not be put in the 'menu' folder
The folder named 'menu' (inside the folder named 'Lua') will have the files for the menu, EXCEPT FOR 'menu.lua'
Only the files specified to be in the folder 'menu' need to be in there
