+      The EspoTek Labrador is an open-source board that turns your PC into a
+      full-featured electronics lab bench, complete with oscilloscope, signal
+      generator, logic analyzer, and more. This package provides the Qt5
+      desktop application for interfacing with the Labrador hardware.
+
+      On NixOS, add `services.udev.packages = [ pkgs.labrador ];` to enable
+      non-root USB access to the device.
