# How to extract a composition from an app

If you want to customize an app template, you'll first need to extract a composition from it. The Dashboard is where you do this. Here's how:

1. Right-click on the app that you'd like to extract a composition from.
2. Select **Extract Composition**. The new composition will appear in the Compositions section of the same fold that contains the control app.
