+If you want to test ioSender with grblHAL but do not have a board yet you can use the [grblHAL simulator](https://github.com/grblHAL/Simulator).
+Build it with the [Web Builder](http://svn.io-engineering.com:8080/?driver=Simulator&board=Windows), unpack the .exe-files in the downloaded .zip somewhere and
+open a command window (cmd or PowerShell) in the folder by \<Shift\>+Right clicking in it, select the _Open PowerShell window here_ or
+_Open command window here_ from the popup menu to open it.
+Then find your computers IP address by typing `ipconfig` - the IP address can be found in the report generated.  
+Run the simulator by typing `./grblHAL_sim -p 23` - 23 is the default Telnet port number and you may have to change it if a Telnet server is already running on the machine.
+Leave the window open.  
+Now start ioSender and select the _Network_ tab in the sender connection dialog, change the port number if you run the simulator with a different port,
+type in your computers IP address and click _Ok_ to connect.  
+You can run gcode programs, jog, access settings etc. but _not_ use gcodes that needs input - e.g. probing.  
+The simulator can be stopped by typing \<Ctrl\>+C in the command window or by closing it.
