Alright, I think I get it. So basically follow that README.md and then follow your debugging guide.
This is my simple Primary.java class.
package com.playground;
import com.google.inject.Inject;
import org.spongepowered.api.event.Subscribe;
import org.spongepowered.api.event.state.PreInitializationEvent;
import org.spongepowered.api.plugin.Plugin;
import java.util.logging.Logger;
/**

@Plugin(id = “playground”, name = “Playground”, version = “0.1”)
public class Primary
{
@Inject Plugin plugin;
@Inject Logger logger;
private static Primary instance; public static Primary getInstance() { return instance; }
public Primary() { instance = this; }
@Subscribe public void onPreInit(PreInitializationEvent e) { logger.info("Playground is loading..."); }
}
