# Reference

{% hint style="warning" %}
**IMPORTANT**: The Merch Bridge relies on Shopify's Draft Order system to gate products. Due to this limitation, support for non-native checkout flows may vary.  Please contact us if you use a non-native checkout flow.
{% endhint %}

{% hint style="warning" %}
**PREREQUISITE**: Make sure you have installed the [Merch Bridge App](broken://pages/n8PtnOQgZAIBugzGd8sJ)
{% endhint %}

These guides will help you add the Merch Bridge to your Shopify Storefront Themes, and set up gated products.

Before you can gate any products, you will need to follow the [Liquid Theme Setup](broken://pages/z5zykf60tbytnqH5kkjZ) guide.
