General Kit Format
The format for a kit is:
kits: kitname: # Change to whatever name you'd like items: '0': 'item' # Item format below '1': 'item' # Item format below '2': 'item' # Item format below
All the way up to 35.
When typing the items, type them like so:
The only section above that is required is the itemID. You may leave the amount and durability part out. If there is no amount, the default is 1.
If you want an enchantment, you must have both the Enchantment ID AND the level.
If you'd like an empty slot, just use a 0.
To add armor, all you need to do is type in the armor type!
kits: kitname: # Change to whatever kit items: helmet: iron chestplate: gold leggings: diamond boots: leather
The color codes for leather armor can be found here.
