Groupmanager How to set it up tutorial.

I saw a lot of theards groupmanager not working or similar to that.

Well this days groupmanager got glitch when you do your permissions in groupmanager/worlds/world/groups.yml

It stop working or crashes.
Here is what I did.
I did the permissions from game.
And It didnt crash or somethink.
To create group do /mangadd (name)
To add permissions do /mangaddp (groupname) (perm1) (perm2) (perm3) (perm4)
Want to add prefix/suffix? /mangaddv (groupname) (variable) (How you want it to look)
What is variable? In this case It is prefix or suffix . If you want to set prefix you put prefix and suffix if you want suffix. If you are fast typer you can do it in 15 minutes. I hope this was helpful. This should work and not crash or stop working groupmanager!
