Is there full tutorial, how to create my own PermissionService?

Hello.
I want to create my own PermissionService.
Can i read some good tutorials?

You can read through the docs and the code of other permissions plugins.

You can, but you won’t find much on Permissions. It’s the second-oldest issue, and it still hasn’t had any progress. If there’s anyone out there that understands Sponge’s permissions API enough to write about it, please help!

I meant the java docs.

Okay, maybe I’ll wait until someone would write about the Permissions API …
I think, when it comes out, it will be placed there?

That is indeed the placeholder. We’re still waiting for someone capable of doing it to volunteer… it’s not a subject that is easily addressed. Until then, as @RandomByte says, you still have the Javadocs.
