SimpleSpleef How to give player permissions

I have setup everything in simplespleef.
But, I have no idea on how to give players perms to join.
Ops can join, but no one else can join. Please help

Simplespleef config:
# Simple Spleef configuration
# Note on materials: If you use numbers for IDs and data values, make sure that you use an amount! E.g.: 1:35:5 or WOOL:5 works, but not 35:5!
# RED_WOOL does not work! Use WOOL:14 instead!
# Also, if you use single item ids (like 42 for iron block, make sure to suround them with ' - e.g. '42'. If you forget to do this, Bukkit
# will interpret the value as integer and bug SimpleSpleef...
# Material ids/names can be found at https://github.com/Bukkit/Bukkit/blob/master/src/main/java/org/bukkit/Material.java
# Version number of configuration - do not touch! It is used for automatic updates of configuration settings.

Do you have a permissions plugin? If so, simply add the permission nodes to join a game to the group the players are in.
