The document discusses the basics of releasing an iOS app to iTunes, including: 1) The code signing process which involves generating keys, uploading the public key to the Apple portal, adding devices, creating an App ID, downloading provisioning profiles for code signing. 2) The distribution process which involves signing the binary, packaging it as an IPA, and distributing via developer profiles connected to devices, ad hoc profiles over-the-air, or submitting to the App Store. 3) The types of provisioning profiles for development or distribution, and differences between ad hoc and App Store distribution profiles. TestFlight is mentioned for easier ad hoc distribution.
