Command accessible for everyone

What was the word I should add in plugin.yml to get a command public accessible? I only know op yet...

Code:

default: true # Everyone can use it
default: false # Nobody can use it
default: op # Only OP can use it
default: notop # Everyone can use it except OP

And though you put

Code:

default: false # Nobody can use it

players that has that command's permission like

Code:

permission: some.permission.node

Will be able to run command and Opposite if not or player has been taken away that permission.

Thanks

Never knew there was notop 0.o xD
