• Shairport Sync is an AirPlay audio player – it plays audio streamed from Apple devices and from AirPlay sources such ForkedDaapd.
• Shairport Sync can be built to support AirPlay 1 only or AirPlay 2. The AirPlay 2 build requires a good deal of extra library support and may not fit into smaller devices.
• AirPlay 2 support is experimental and incomplete. The focus of the development effort is on good audio performance. Thus, many out-of-scope features are missing or broken. So integration with Apple's Home app is missing; remote control doesn't work.
• When built for AirPlay 1, Shairport Sync runs on Linux, FreeBSD and OpenBSD.
• AirPlay 2 support is only available on recent Linux builds.

• A brief guide to building Shairport Sync for AirPlay 1 is available at BUILDFORAP1.md.
• To build Shairport Sync for AirPlay 2, please follow the guide at BUILDFORAP2.md.

Shairport Sync does not support AirPlay video or photo streaming.

For the development of AirPlay 2 support, special thanks are due to:

• JD Smith for really thorough testing, support and encouragement.
• ejurgensen for advice and code to deal with pairing and encryption.
• ckdo for pointing the way, particularly with pairing and encryption protocols, with a functional Python implementation of AirPlay 2.
• invano for showing what might be possible and for initial Python development.
• Charles Omer for testing, encouragement and enthusiasm.

And of course, thanks to everyone who has supported and improved Shairport Sync over the years.
