Create a new Bukkit plugin as you did in Chapter 3, Creating your First Bukkit Plugin, but name it Enchanter. Next we will inform Bukkit that you will be using a command by modifying the plugin.yml file of your plugin.
As mentioned in Chapter 2, Learning the Bukkit API, Bukkit reads the YAML file in order to find out the necessary information about your plugin.
