 ## Announcement and Public Beta
 
-We are announcing Haven today, as an open-source project, along with a public beta release of the app. We are looking for contributors who understand that physical security is as important as digital, and who have an understanding and compassion for the kind of threats faced by the users and communities we want to support. We also think it is really cool, cutting edge, and making use of encrypted messaging and onion routing in whole new ways.
