Custom Vending

In the config - how do I put custom vending. Is there a default config I can reference. It says this:
 

  "Custom Vending Machines (Entity ID - settings)": {},

  "Settings available containers for selling item": {

    "Enabled": true,

    "Available Containers (main, belt, wear)": [

      "main",

      "belt"

    ]

  },

Does it replicate the NPC shop settings - like this :

 

  "NPC Shops (NPC ID - shop categories)": {

    "7407040000": {

      "Permission": "",

      "Categories (Titles) [* - all]": [

        "*"

      ]

    },



Or is it different?

The Shop plugin has the following commands:

- shop.setvm [categories: cat1 cat2 ...] - add custom VM in config

- shop.setnpc [categories: cat1 cat2 ...] - add NPC in config

Yes - that's is my question.

I added the config above - there is no information of what would fall under settings.

what is the outline for the vending , all it has is brackets and says (vending id - settings)

Example settings in the config:

  "Custom Vending Machines (Entity ID - settings)": {
    "20614693": {
      "Permissions": "",
      "Categories (Titles) [* - all]": [
        "Items"
      ]
    }
  },

 Thanks!
