Creating a YWML Mod from Scratch

1. Sort your mod files in a loose fashion inside an include folder. For example, if I edited data/menu/title_screen.xa, This is how my folder structure will look:

   -MyMod
    -include
        -data
            -menu
                -title_screen.xa
   

2. Right outside of the include folder, create a file called ywml.json and paste the following into it:

   {
    "Name": "Your mod's name",
    "Author": "Your name",
    "Version": "Your mod's version"
   }
   

Fill out all of the fields!

But wait, what if you edited files that are already loose, like files in mov or snd? Well, it’s super simple to integrate! Simply paste your mov and snd folders, for example, right outside the include folder!

Your mod is now ready to load with YWML!

Happy Mod Loading!
