Installing the KudosWall widget takes one step: paste a ` ``` **Next.js** — Use the built-in ` ``` Click **Save** in Page Settings, then publish your site. The widget will appear at the location where the script tag is injected. To control exactly where on the page the widget appears in Webflow, add an **Embed** element (from the Add panel) to your canvas and paste the script tag inside it. This lets you position the widget precisely within your layout. The most reliable way to add the widget to a Shopify store is to edit `theme.liquid` directly. In your Shopify admin, go to **Online Store** > **Themes**. Next to your active theme, click the **three-dot menu** and select **Edit code**. In the file list on the left, find and click **`theme.liquid`** under the **Layout** folder. Use your browser's find function (Ctrl+F or Cmd+F) to search for `` near the bottom of the file. Paste the KudosWall script tag just before ``: ```html theme={null} ``` Click **Save**. The widget is now active on all pages that use this layout. To show it on a specific page only, add the script to that page's template file instead. ## After installing Once the script is on your page, all future widget updates — layout changes, new testimonials, filter adjustments — happen automatically from your KudosWall dashboard. You don't need to touch your site's code again. Customize your widget's layout, theme, and filters. Fix common issues with widget display and placement.
