# GiveBackStuffOnResets by drtshock
# This plugin is designed to execute commands when a player first joins the server based on their primary group.
# Great for giving people money and mcmmo etc. back on resets.


# Add as many groups as you want. Group names are case sensitive to what you have defined in your permissions plugin.
# Add commands to execute as a list below the key.
# Use {name} for the player's name.

default:
  - "/give {name} diamond 1"
