+--------------------------------------------------------------------------------
+
+[> Getting started
+------------------
+1. Obtain MiSoC and follow its "Quick start guide". Set the MSCDIR environment
+  variable to the MiSoC directory.
+
+2. Build design:
+  make all
+  
+3. Load design:
+  make load
+
+4. Run test:
+  make test
+
+[> Cores :
+  - UART2Wishbone bridge
