It’s official, Facebook has opened its App Center, an app store within the social network. It launches with about 600 apps, including Pinterest, Instagram and Airbnb. More apps are expected to roll out in the coming weeks.

In May, Facebook announced the new app store, which includes iOS, Android, web and mobile web apps.

Facebook’s Matt Wyndowe explains how to apps from the App Center to your mobile phone. In a blog post, he writes: “To make it easier to find social apps for mobile, the App Center is available in the Facebook iOS and Android apps, as well as Facebook.com. You can send apps you find on your computer to your mobile device using the new ‘Send to Mobile’ feature. If a mobile app requires a download, you’ll be sent to install it from the Apple App Store or Google Play.”
