## Enable the App Extension in Your Theme

Fabric Lens requires adding an app block to your Shopify theme so the pattern visualizer displays on your product pages. No code required.

1. In your Shopify admin, go to **Online Store > Themes**.
2. Click **Customize** on your active theme.
3. Navigate to the product page template in the theme editor.
4. Click **Add block** or **Add section** and search for **Fabric Lens**. Select and add the app block.
5. Position the block on the page where you want the pattern visualizer to appear.
6. Click **Save**.

<Note>
  You can also enable the extension directly from the Dashboard by clicking Step 1: Enable extension on your store.
