+Running LVGL
+============
+
+It is possible to run the LVGL Demo directly in the NuttX simulator ::
+
+    $ make distclean
+
+    $ ./tools/configure.sh sim:lvgl
+
+    $ make -j
+
+    $ ./nuttx
+
+You should see a window with the touch calibration and then the LVGL demo:

+
+Running VNC Server
+==================
+
+NuttX supports a VNC server, so it means even boards without a LCD display
+could export a display interface over network. Also you can test it on NuttX
+simulator before getting it working on your board, just follow these steps ::
+
+    $ make distclean
+
+    $ ./tools/configure.sh sim:vncserver
+
+    $ make -j
+
+    $ ./nuttx
+
+Open a new terminal and execute ::
+
+    $ remmina -c vnc://localhost
+
+You should see some squares in different colors displayed in remmina:
