-This program makes the FHZ1000/FHZ1300/WS300 and other USB devices sold by ELV,
-Conrad and others as well as X10 devices sold by Marmitek, Powerhouse and
-others useable with Linux. In fact, there is nothing Linux special
-in it, there are reports from OS X and Windows. You should be able to use it on
-other platforms as long as you can access the hardware as a serial device.<br>
+<b>fhem</b> is used to automate some common tasks in the household like
+switching lamps/shutters/heating/etc. and to log events like
+temperature/humidity/power consumption.<br><br>

 The program runs as a server, you can control it via telnet, command line
 program or TCP/IP directly, like the supplied web frontends do.<br> <br>
