 This small sketch tests the USB host shield mass storage library.
 
+__Note:__ This will not run a Arduino Uno due to the limited ram available in the ATmega328p.
+
 To compile this example you will need the following libraries as well:
 
 * [xmem2](https://github.com/xxxajk/xmem2)
 * [generic_storage FATfs](https://github.com/xxxajk/generic_storage)
 
-It is recommended to use the bundled [Makefile](Makefile).
+It is recommended to get a external RAM shield and apply the following patch: <https://github.com/arduino/Arduino/issues/1425>.
 
-The master makefile can be found at the following repository: <https://github.com/xxxajk/Arduino_Makefile_master>.

+The following shield is recommended: <http://ruggedcircuits.com/html/quadram.html>.
+
+You must use the bundled [Makefile](Makefile) to compile the code instead of the Arduino IDE if you do not use external RAM.
+
+To download the USB Host library and all the needed libraries for this test.
+
+Run the following command in a terminal application:
+
+```
+git clone --recursive https://github.com/felis/USB_Host_Shield_2.0
+```
+
+If you want to update all the submodules run:
+
+```
+git submodule foreach --recursive git pull origin master
+```
