 """
 LIRC interface to receive signals from a infrared remote control.
 
-This sensor will momentarily set state to various values as defined
-in the .lintrc file which can be interpreted in home-assistant to
-trigger various actions.
-
-Sending signals to other IR receivers can be accomplished with the
-shell_command component and the irsend command for now.
+For more details about this component, please refer to the documentation at
