How to create new tags?

Tags will appear in the same order of creationg, to create new rewards simply follow the following format:

Tags:
  #Tag identifier. This MUST BE UNIQUE for the same tag.
  #You can setup your tags in one server and then copy tags.yml
  #to others. Make sure they are the same in all server.
  new-tag:
    #You can use any material you want. Due to API changes and to be able to keep compatibility 1.8 - 1.16 durability
    #is not supported in any version. Only materials. You can also use "CUSTOM_HEAD" to make the item a custom head with texture.
    #If "CUSTOM_HEAD" is necessary to specify "Texture", otherwise default texture will be used.
    #An additional material type was added. "RANDOM" will select a random material when server starts. IT WON'T DISPLAY A RANDOM MATERIAL EVERY TIME YOU OPEN THE GUI.
    #Random material will be selected JUST ON RESTART/RELOAD.
    #DURABILITY IS AVAILABLE ONLY IN PREMIUM VERSION!
    Material: CUSTOM_HEAD
    #This is only available in 1.14+
    #This option allows you to use a CUSTOM textures for this item (using a texture pack)
    #Leave it as 0 if you don't plan to use it or don't know how. THIS WILL NOT WORK IF MATERIAL IS CUSTOM_HEAD
    Custom-model-data: 0
    #Texture MUST be specified if material is CUSTOM_HEAD otherwise our default texture will be used.
    Texture: "eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzMwZmVhNDQzNDlmMDczZjNmOTNjZTg2ZWM5ZWVlODJmODRhMWM1ZTI5NjdlYjFjMTliN2MzNWY5YTVlNWY5OSJ9fX0="
    #Pattern is only necessary if material is a valid banner material.
    #For compatibility and to make it easy for owners to make banners you MUST use banner materials from 1.13+
    #It means you MUST use materials like: WHITE_BANNER, RED_BANNER, PINK_BANNER, etc..
    #To make it even easier for you to create banners you can use this website: https://minecraft.tools/en/banner.php
    #How to get this? Go to the page above and create one banner or get one from gallery.
    #If you create a banner click on "Craft this banner". You'll see now give commands for 1.13+ and legacy version.
    #PICK THE ONE FOR YOUR VERSION! If you use 1.8 - 1.12 then pick "/give command syntax (1.8 to 1.12):" otherwise use "/give command syntax (1.13+):" command.
    #IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT! IMPORTANT!
    #You must copy ONLY what it inside braces { }.
    #Example: /give @p minecraft:banner 1 0 {BlockEntityTag:{Patterns:[{Color:15,Pattern:"mc"}]}}  => You only use '{BlockEntityTag:{Patterns:[{Color:15,Pattern:"mc"}]}}'
    #Example: /give @p minecraft:black_banner{BlockEntityTag:{Patterns:[{Color:0,Pattern:"mc"}]}}  => You only use '{BlockEntityTag:{Patterns:[{Color:0,Pattern:"mc"}]}}'
    #REMEMBER, ONLY WHATS INSIDE BRACES! { }
    #If string contains " you must escape them by adding a backslash before as in the example below. DO NOT ESCAPE FIRST AND LAST ONE.
    #Quick reminder, the material you need to use is in the 1.13+ command version. Material is BLACK_BANNER in the example.
    Pattern: "{BlockEntityTag:{Patterns:[{Color:11,Pattern:\"flo\"},{Color:15,Pattern:\"mr\"},{Color:15,Pattern:\"cbo\"},{Color:1,Pattern:\"mc\"},{Color:15,Pattern:\"tt\"}]}}"
    #Should the tag be dyeable? DEFAULT or not specified it will be considered as false.
    #If true, color gui will be opened if tag is selected.
    Dyeable: true
    #Default color for the tag. Remember that this will be the default color and all players with access
    #to the tag will have access to it.
    Default-color: "&6"
    #Should flags be hidden for this tag icon?
    #If true all flags will be hidden, including unbreakable, potion effects, patterns, damage, speed, etc
    Hide-flags: true
    #Tag that will be displayed. Don't use spaces before or after the tag. You can use spaces IN the tag.
    #Example: Don't do this: "   &6[MY TAG]   ", just do "&6[MY TAG]"
    #REMEMBER: If you set Dyeable to true, you MUST include {COLOR} string in Tag to
    Tag: "{COLOR}[NEW]"
    #Recommended to add "{COLOR}" before the text. This will be replaced with color red to show player doesn't have access to the tag.
    Displayname: "&7&l{COLOR}Starter Tag"
    #Recognition title. CURRENTLY NOT USED. IGNORE IT.
    #{COLOR} is allowed here if tag is Dyeable.

    Permission: "none"
    #Price for the tag. Set to 0 if tag can't be purchased. If permission is "none" too tag will be free.
