+Introduction to the pyboard
+===========================
+
+To get the most out of your pyboard, there are a few basic things to
+understand about how it works.
+
+Caring for your pyboard
+-----------------------
+
+Because the pyboard does not have a housing it needs a bit of care:
+
+  - Be gentle when plugging/unplugging the USB cable.  Whilst the USB connector
+    is soldered through the board and is relatively strong, if it breaks off
+    it can be very difficult to fix.
+
+  - Static electricity can shock the components on the pyboard and destroy them.
+    If you experience a lot of static electricity in your area (eg dry and cold
+    climates), take extra care not to shock the pyboard.  If your pyboard came
+    in a black plastic box, then this box is the best way to store and carry the
+    pyboard as it is an anti-static box (it is made of a conductive plastic, with
+    conductive foam inside).
+
+As long as you take care of the hardware, you should be okay.  It's almost
+impossible to break the software on the pyboard, so feel free to play around
+with writing code as much as you like.  If the filesystem gets corrupt, see
+below on how to reset it.  In the worst case you might need to reflash the
+MicroPython software, but that can be done over USB.
+
+Layout of the pyboard
+---------------------
+
+The micro USB connector is on the top right, the micro SD card slot on
+the top left of the board.  There are 4 LEDs between the SD slot and
+USB connector.  The colours are: red on the bottom, then green, orange,
+and blue on the top.  There are 2 switches: the right one is the reset
+switch, the left is the user switch.
+
+Plugging in and powering on
+---------------------------
+
+The pyboard can be powered via USB.  Connect it to your PC via a micro USB
+cable.  There is only one way that the cable will fit.  Once connected,
+the green LED on the board should flash quickly.
+
+Powering by an external power source
+------------------------------------
+
+The pyboard can be powered by a battery or other external power source.
+
+**Be sure to connect the positive lead of the power supply to VIN, and
+ground to GND.  There is no polarity protection on the pyboard so you
+must be careful when connecting anything to VIN.**
+
+**The input voltage must be between 3.6V and 10V.**
