+    longDescription = ''
+      Bluez-ALSA (BlueALSA) is an ALSA backend for Bluez 5 audio interface.
+      Bluez-ALSA registers all Bluetooth devices with audio profiles in Bluez
+      under a virtual ALSA PCM device called `bluealsa` that supports both
+      playback and capture.
+
+      Some backstory: Bluez 5 removed built-in support for ALSA in favor of a
+      generic interface for 3rd party appliations. Thereafter, PulseAudio
+      implemented a backend for that interface and became the only way to get
+      Bluetooth audio with Bluez 5. Users prefering ALSA stayed on Bluez 4.
+      However, Bluez 4 eventually became deprecated.
+
+      This package is a rebirth of a direct interface between ALSA and Bluez 5,
+      that, unlike PulseAudio, provides KISS near-metal-like experience. It is
+      not possible to run BluezALSA and PulseAudio Bluetooth at the same time
+      due to limitations in Bluez, but it is possible to run PulseAudio over
+      BluezALSA if you disable `bluetooth-discover` and `bluez5-discover`
+      modules in PA and configure it to play/capture sound over `bluealsa` PCM.
