# Related Applications

The `prefer_related_applications` member is a boolean value that specifies that applications listed in `related_applications` should be preferred over the web application.

If the `prefer_related_applications` member is set to `true`, the user agent might suggest installing one of the related applications instead of this web application.

{% code title="/config/packages/pwa.yaml" lineNumbers="true" %}

```yaml
pwa:
    manifest:
        prefer_related_applications: true
        related_applications:
            - platform: "play"
