 # lxqt-session
 
+Tools to handle LXQt sessions.
+First of all there's session manager lxqt-session. The binary is launched right at the beginning of LXQt sessions and in turn responsible for launching and monitoring all other components constituting the sessions.
+GUI "LXQt Session Settings" (binary lxqt-config-session) is used to configure various settings affecting the session, e. g. which window manager to use or which applications to start automatically.
+Binary lxqt-leave deals with interrupting or terminating sessions. It comes with several options expressing the action they trigger, e. g. --leave, --hibernate, --shutdown or --reboot.
