Loadout is a mod made for Mod Pack Makers. It allows you to specify a set or sets of items to give to Players the first time they log into the game. You are able to specify multiple loadouts in case you need to add additional items at a later point. Item Loadouts are stored in

.minecraft\config\grimco\loadouts.json

The expected syntax for the loadouts.json is similar to what vanilla uses for recipes. The follow bit of code creates a Loadout called 'basic' that gives players 32 Torches, 8 Apples, 1 Stone Pickaxe, 4 Birch Saplings, and 1 Potion of Healing

{
  "basic": [
    {
      "item": "minecraft:torch",
      "count": 32
    },
    {
      "item": "minecraft:apple",
      "count": 8
    },
    {
      "item": "minecraft:stone_pickaxe"
    },
    {
      "item": "minecraft:sapling",
      "data": 2,
      "count": 4
    },
    {
      "nbt": "{Potion:\"minecraft:healing\"}",
      "item": "minecraft:potion",
      "type": "minecraft:item_nbt"
    }
  ]
}

It's pretty straight forward, and easy to tweak by hand if needed. There is an easier way however.

Loadout also offers some commands that Creative Players or those who are OP on server can access

The primary command, /LO, has 6 default arguments. Create, Delete, List, View, Reload, and Help.

/LO CREATE <NAME>
- When used, the command creates a Loadout with the given name based on the contents of your inventory. It will automatically be added to the loadout.json in the config directory. Loadout names must be unique. If you reuse a Loadout name, it will overwrite the previous Loadout. To activate the Loadout you will need to restart the server/your client in a single player setting OR use /LO RELOAD
/LO DELETE <NAME>
- Deletes the current active Loadout with the given name. This will remove it from the Loadout json file as well. There is no undo for this, so use it with care.
/LO LIST
- Lists all current active loadouts
/LO VIEW <NAME>
- Displays the items that will be given by the given loadout, including Item Name, Data (meta), Count, and NBT
/LO RELOAD
- Reloads all Loadouts from the Loadout json, useful if you're manually tweaking stuff.
/LO HELP <CREATE|DELETE|LIST|VIEW|RELOAD|HELP>
- Displays the proper syntax for the passed argument and gives a short description as to it's function.
  - Who Helps the Help?

When a player log's in for the first time, the Mod checks to see if a player has previously received the current active Loadouts, if they haven't the player is granted the items specified and then tagged as having received the items preventing any further items from being given.
