 This command will install required and some optional dependencies that will enable most of the commonly used functionality of monado on Debian/Ubuntu.
 Some features and drivers are only compiled with additional dependencies like libsurvive or librealsense.

 Most monado developers and users who want exact control over when Monado is running are expected to run `monado-service` manually.
 
-A manually started `monado-service` is cleanly shut down by simply pressing enter in the terminal it was started in.

-An unclean shutdown (ctrl+c, crash) will leave a socket file `/run/user/1007/monado_comp_ipc`. If Monado's build configuration includes the `libbsd` library, this unused socket file will be automatically cleaned up by the next monado run. If Monado was built without support for `libbsd`, the Monado compositor will refuse to start if this file is found an error message. It safe to simply delete this file, as long as `monado-service` is not running - it holds no information, it is only used for live communication between monado-service and OpenXR applications.
+A manually started `monado-service` is cleanly shut down by simply pressing enter in the terminal it was started in. An unclean shutdown (ctrl+c, crash) will leave a socket file `/run/user/1007/monado_comp_ipc` that gets deleted when Monado starts again.
 
 
 If systemd is available (and it's not configured to disable this), a monado.socket and monado.service user unit files are installed in /usr/lib/systemd/user or similar. `systemctl --user enable monado.socket` will have systemd open the domain socket at login. Running an OpenXR application will spin up the service, while `systemctl --user stop monado.service` will stop it. This is expected to mainly be used by end users installing a package.
