 # Compiling your project
 
-The extension requires that your project is built against version 5 of the iOS SDK.  
-It doesn't require version 5 at run-time (version 4 is sufficient), but it is required at compile-time.
+The extension requires that your project is built against version 5.1 of the iOS SDK.  
+It doesn't require version 5.1 at run-time, version 4.0 should be sufficient, but it is required at compile-time.
 Due to this limitation, any project using the extension must be compiled on a computer running Mac OS X and with version 5 or later of the iOS SDK. Specify the path to the SDK when compiling the project, if the functionality is built in to your IDE (like in Flash Builder) or using parameter **-platformsdk** when building with adt from the command line or a build script.  
 Use Adobe Air SDK 3.3 or later.
