There are two types of bundles in Bundle Builder: Single SKU and Multiple SKU. It's essential that you choose the right one for your business.
Single SKU Bundle Installation
Installation for Single SKU bundles happens automatically when you install the app on your theme of choice. You can check on the status of the installation by heading to Settings > Installation.
The installation process will install a single template in your current theme. The file is called
product.bundlebuilder.liquid and will be in your 'Templates' folder. This file ensures customers are automatically navigated to your bundle page.
Multiple SKU Bundle Installation
