# Customizing App

Customizing App is the next step once the app is installed from **Valorx App Store**. Designers can customize the app before installing the app or even after the installation.

Click on **Valorx App Store** and Click on **GET**. APP Customization : User Management page will open.

Click on **Customize** option and a page will open. On the left hand we will find the APP and on the right hand we can see the unused fields from **CRM**. Designers can just drag and drop the unused fields if they want to add them to the app, and click on **Apply changes**.
