+migScope is a small logic analyzer to be embedded in an FPGA.
-or external signals.
+
+While free vendor toolchains are generally used by beginners or for prototyping 
+(situations   where   having a logic  analyser  in  the design is generally very 
+helpful) free  toolchains are  always  provided  without  the proprietary logic 
+analyzer solution... :(
+
+Based on   Migen,   migScope   aims  to  provide a free, portable and flexible 
+alternative to vendor's solutions!
+
+[> Specification:
+
+migScope provides Migen cores to be embedded in the design and Python drivers to 
+control the logic  analyzer  from the Host. migScope automatically interconnects 
+all cores  tothe CSR bus. When using Python on the Host, no needs to worry about
+cores register mapping, importing migScope project gives you direct access to 
+all the cores!
+
+migScope 	produces.vcd output files to be  analyzed  in your favorite waveform 
+viewer.
 
 [> Status:
-Early development phase
+Complete flow tested on board with a classic Term. RangeDetector, EdgeDetector 
+still not tested.
 
-Simulation:
