## Checking If Your PWA is Store-Ready
PWA Studio can evaluate and validate your PWA to ensure it is both [installable from the browser](https://docs.microsoft.com/en-us/microsoft-edge/progressive-web-apps-chromium/ux#installing-a-pwa) and ready to publish to the app stores.
To validate your PWA:
1. Navigate to the PWA Studio pane by clicking the icon the left-most bar of VS Code.
2. The bottom most section of the PWA Studio pane has a checklist where you can see what your PWA has and what it is missing.
3. Evaluate what your PWA needs to be store-ready.
The checklist should look like this:
In the example above, you can see that our app has the necessary features of a PWA, but hasn't yet be published to the web. As a result, the store-ready check fails overall.
If your PWA is missing some features (like a service worker or web manifest), learn how to [Convert an Existing Web App](https://github.com/pwa-builder/pwabuilder-vscode/wiki/Convert-an-Existing-Web-App) to a PWA.
