# MirrorSim third-party notices

MirrorSim release packages include a native AirPlay receiver built from the
public `Mahcks/AirPlayServer` fork. The exact source used for a release is the
AirPlayServer tag referenced by `receivers/runtime-manifest.json`. The
AirPlayServer repository's top-level MIT license does not replace the separate
licenses carried by third-party code compiled into the receiver runtime.
