+
+BeagleV Ahead is an open-source RISC-V Single Board Computer (SBC) in the form 
+factor of BeagleBone Black. It has the same P8 & P9 cape header pins allowing you 
+to stack your favourite BeagleBone cape on top to expand it's capability. 
+It's designed as an affordable RISC-V enabled pocket-size computer for anybody 
+who want's to dive deep into the new RISC-V ISA.
