We are having a terrible time getting the kit portion of the plugin working. I have read this forum and the documentation several times. I understand the concept of custom kits and kits from the plugin. No matter what we do, the plugin defaults to the loadout with the hunting bow, 50 arrows, stone spear, etc. 

Some things we have tried

Modifying the Custom Kits in Duelist.json
Changing the names of custom kits will show up in /duel kit 
Changing the quantity (ie of ammo stack) or changing any items in the json has no effect
Deleted all files in config, data, lang, plugin, etc and restarted server then reinstalled plugin
Tried modifying the CS file directly

When first installed the plugin worked. Any changes we try  to make seems to break the plugin. All we want to do is make our own load outs for the duel. 

Can you please explain exactly what to modify in the custom list? Can you show an example from the json of what to modify?
Can you please post a link to the kit plugin that works with duelist? We have installed RoKKit and it does not seem compatible with Rust. We have used Rust Kits but that does not seem to work with Duelist.

I hope you can please help us. This is the most fun plugin or group has ever used. We are trying to build a server around the functionality of this plugin. But, if we cant get our own kits in there it makes it hard for us to use. I would be happy to help out with a quickstart guide once I understand exactly how this works.
Is this the right place to change custom kits? Any changes we have made here never seem to show up in duels.

 "Custom Kits": {
    "Kits": {
      "Assault Rifle and Bolt Action Rifle": [
        {
          "ammo": "ammo.rifle",
          "amount": 1,
          "container": "belt",
          "mods": [
            "weapon.mod.lasersight"
          ],
          "shortname": "rifle.ak",
          "skin": 0,
          "slot": -1
        },
        {
          "ammo": "ammo.rifle",
          "amount": 1,
          "container": "belt",
          "mods": [
            "weapon.mod.lasersight",
            "weapon.mod.small.scope"
          ],
          "shortname": "rifle.bolt",
          "skin": 0,
          "slot": -1
        },

Is this where we add kits into rotation?

"Disable Requirement To Allow Duels": false,
    "Duel Command Name": "duel",
    "Immunity Time": 10,
    "Kits": [
      "kit_1",
      "kit_2",
      "kit_3"
    ],
    "Kits Least Used": [
      "kit_4",
      "kit_5",
      "kit_6"
    ],
    "Kits Least Used Chance": 0.25,

So, where are kit_1, kit_2, etc? How can I modify those kits? I have tried erasing the references in this part of the json. As I understand from the docs, this should force the plugin to pull from the custom kits in the json at about line 66. But, nothing seems to change when we delete these kits.

Question. If we delete the kit_x reference from kits and kits least used, does the plugin automatically choose from the custom kits at line 66? Does it choose in order or random? Do we have to put the name from custom kit into the kit and least used kit sections to make it choose them?

How can we edit kit_1, kit_2, etc?

We have been wrestling with this plugin for a couple days. We really want to find the simplest way to just change kits. Any help is greatly appreciated. Let me know how I can help you back.

Thank you

Well I got this working. I think the problem was in my understanding of the documentation. If anyone else is having this issue I hope this helps.
I was confused about all the references to kits. I dont think this actually works with a kit plugin. This is how we made it work.

Edit the kit configurations located below line 66 "custom kits"
Change the name of these kits and add remove items and quantities using the format in the json

Once they are setup the way you like look for the "kits" and "kits least used" section (around line 637)
It should say kit_1 kit_2 etc. 
Change the name of these to match the names you used above in custom kits.
Remember there is no , after the last item in the list.

Now it will pull the kits from the custom ones in the json file.

Custom Kits section around line 66
