+As an open-source and app-centric container platform, KubeSphere integrates 15 built-in apps in the App Store that is based on [OpenPitrix](https://github.com/openpitrix/openpitrix). They are accessible to all tenants in a workspace, while you can also remove them from the App Store. This tutorial demonstrates how to remove a built-in app from the App Store.
+
+## Prerequisites
+
+- You need to use an account with the role of `platform-admin` (e.g. `admin`) for this tutorial.
+- You need to [enable the App Store](../../../pluggable-components/app-store/).
+
+## Remove a Built-in App
+
+1. Log in to the web console of KubeSphere as `admin`, click **Platform** in the upper left corner, and then select **App Store Management**.
