+#### Update to AweSim Appkit 1.0
+
+To transition your app to the OOD infrastructure, your app must be compatible with the AweSim appkit v1.0.
+
+To upgrade to the AweSim appkit v1.0, please see the [guide](https://apps.awesim.org/awesim_dev/dashboard/docs/Port-an-existing-app-to-AppKit-1.0).
+
+#### Update Rails
+
 Due to changes in the OOD gems, OOD applications will need to have a _minimum_ Rails version of **`4.1.15`**, you can also update to the latest version of Rails **`4.2`**.  Rails 5.0 is not yet supported.
 
 We will be replacing the `awesim_rails` gem with the `ood_appkit` gem, and updating the rest of the OOD dependencies to work with the latest version of OodAppkit.
