I'm stuck on the 2nd part of creating an item where do I edit the do i make a new class project or do i add it to the bottom of the code thats there im kinda stupid

ok so i know how to make the recipe for the item i want to make which is just iron armor fused with diamond armor to make an improved armor what im lost on is how to create the actual item itself and how to apply the texture to said item This is what i have so far as a test var recipes = require('recipes'); var items = require('items'); ... var UpgradedChestplateRecipe = recipes.create( { result: UpgradedChestplate, ingredients: { I: items.Iron_Chestplate(1), S: items.slime_ball(1), D: items.Diamond_Chestplate(1) }, shape: [ 'ISD' ] } ); // add to server var addedRecipe = server.addRecipe( UpgradedChestplateRecipe );
