Loading Storing a configuration file

Once you have a configuration class, you can then load/store it using th ConfigFile class.
To load it when your mod starts, you could do something like this:

public class Mod implements ModInitializer {
    public static final ExampleConfig config = new ExampleConfig();
    
    @Override
    public void onInitialize() {
        // need to catch exceptions that load and store can produce
        try {
            // load in the values, this will also store defaults on first time*
            // All paths are relative to the .minecraft folder
            ConfigFile.load("./config/example.conf", config);
        }catch(IOException | IllegalAccessException e) {
            throw new RuntimeException(e);
        }
        
        /*
            Do stuff here
        */
    }
}
