Plugin Help on Making a Plugin

Can somebody help me on setting up a plugin using the new API? I have gone to a couple GitHub pages on this but they don't make much sense. I know PHP but it is still a little confusing (not PHP but setting up the plugin).
Thanks​

Example plugins, useful for looking at basic setup. Browse through the commits to see how I did it step by step.

Thanks. Could you tell me what the Main is?

Main is the main class of the plugin, where PocketMine loads this code and this code will ask PocketMine to do things.

Thank you PEMapModder !
