 ## Testing
 
+### 1. Validate Associated Domains
+
+Verify that your app's entitlements file includes the correct associated domains.
+
+Ensure that the `.well-known/apple-app-site-association` file is accessible by going to `"https://{your_storefront_domain}/.well-known/apple-app-site-association"`. Remember that this file will only be accesible on a custom hosted domain, and not a "*.myshopify.com" domain.
+
+### 2. Trigger a Universal Link from terminal
+
 With Universal Links set up, you can test the implementation in the simulator by triggering URLs manually with:
 
 ```sh
 xcrun simctl openurl booted https://www.example.com/cart
 ```
 
-## Troubleshooting
+### 3. Universal Links Diagnostics (real device only)
