 ==============
 This project contains a set of configurations for [WISEBED](http://wisebed.eu) experiments. 
 
+How to use them
+-------------
+Copy the link to a .json file and go to the [WISEBED testbed GUI](http://wisebed.eu/site/testbed). 
+Select a testbed, log in, create a reservation for a set of nodes, select this reservation, and go to
+the "Flash"-dialog. There, click on the "Load" button and paste the URL into the textfield and click ok.
+
+This configuration will be loaded and can afterwards be used to flash the nodes.
+
 How does it work
 -------------
-A configuration is a simple file that specifies which sensor nodes should be flashed with a certain binary. A configuration is a simple JSON-file containing so-called "configuration"-entries.
