+  <p>
+   SocExplorer is an open source generic System On Chip testing software/framework. 
+We write this software for the development and the validation of our instrument, 
+the Low Frequency Receiver(LFR) for the Solar Orbiter mission. This instrument is 
+based on an actel FPGA hosting a LEON3FT processor and some peripherals. To 
+make it more collaborative, we use a plugin based system, the main executable is 
+SocExplorer then all the functionality are provided by plugins. Like this 
+everybody can provide his set of plugins to handle a new SOC or just a new 
+peripheral. SocExplorer uses PythonQt to allow user to automate some tasks such 
+as loading some plugins, configuring them and talking with his device.
