# Cart Page

Before App can start working on your store, you will need to install the app into your current theme.

**Let's start installing the app on cart page** 

1\. Starting from your Shopify dashboard, click on **Online Store**, and then click on **Themes**.

2\. Click the **Actions** ▼ button, then select **Edit code** 

3\. In the top left corner of the theme code editor, search for your **cart.liquid** file and click into it.

4\. If you see that your cart.liquid file is guiding you to your cart-template.liquid file. Go into the **cart-template.liquid** file under the Sections folder.
