+## Automatic Software Updates
+Automatic software updates allow distribution of updates directly to the end users.
+This is useful for general feature updates, bug fixes and especially for security
+updates.
+
+### Automatic Software Updates for Mac OS X using Sparkle
+Swift supports integration with the software update framework [Sparkle](https://sparkle-project.org/) on OS X. For security reasons,
+Sparkle requires the application to be either code-signed or a bundled public DSA
+key. In case you do not code-sign, you can provide the path to the public DSA key
+to be bundled with the application bundle via the `sparkle_public_dsa_key` SCons
+argument.
+
+To build with Sparkle support, simply download Sparkle-1.14.0 and extract it to
+`3rdParty/Sparkle/Sparkle-1.14.0`. SCons will pick it up during configuration
+and build Swift with Sparkle support.
+
+The appcast URL is specified as a compile time preprocessor variable `SWIFT_APPCAST_URL`
+in `Swift/QtUI/QtSwift.cpp`
