       TinyEMU is a system emulator for the RISC-V and x86 architectures. Its
       purpose is to be small and simple while being complete.
+
+      Main features:
+
+      - RISC-V system emulator supporting the RV128IMAFDQC base ISA (user level
+        ISA version 2.2, priviledged architecture version 1.10) including:
+        - 32/64/128 bit integer registers
+        - 32/64/128 bit floating point instructions (using the SoftFP Library)
+        - Compressed instructions
+        - Dynamic XLEN change
+      - x86 system emulator based on KVM
+      - VirtIO console, network, block device, input and 9P filesystem
+      - Graphical display with SDL
+      - JSON configuration file
+      - Remote HTTP block device and filesystem
+      - Small code, easy to modify, few external dependancies
+      - Javascript version running Linux and Windows 2000.
