The document discusses wireless distribution of apps to testers. It describes the traditional method of sending the app and provisioning profile to testers as long, boring, and error-prone. The wireless method allows testers to receive a link by email or SMS to install the app. Developers can use tools like iOS Beta Builder or HockeyApp to generate a manifest file and upload the app files to a server, then send testers a link to install the app wirelessly. This wireless approach makes app testing easier for both testers and developers.
