+Introduction to the WiPy
+========================
+
+To get the most out of your WiPy, there are a few basic things to
+understand about how it works.
+
+Caring for your WiPy and expansion board
+----------------------------------------
+
+Because the WiPy/expansion board does not have a housing it needs a bit of care:
+
+  - Be gentle when plugging/unplugging the USB cable.  Whilst the USB connector
+    is well soldered and is relatively strong, if it breaks off it can be very
+    difficult to fix.
+
+  - Static electricity can shock the components on the WiPy 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 WiPy.  If your WiPy came
+    in a ESD bag, then this bag is the best way to store and carry the
+    WiPy as it will protect it against static discharges.
+
+As long as you take care of the hardware, you should be okay.  It's almost
+impossible to break the software on the WiPy, 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 do a safe boot,
+which is explained in detail in :ref:`wipy_boot_modes`.
+
+Plugging into the expansion board and powering on
+-------------------------------------------------
+
+The expansion board can power the WiPy via USB. The WiPy comes with a sticker
+on top of the RF shield that labels all pins, and this should match the label
+numbers on the expansion board headers. When plugging it in, the WiPy antenna
+will end up on top of the SD card connector of the expansion board. A video
+showing how to do this can be found `here on YouTube <https://www.youtube.com/watch?v=47D9MZ9zFQw>`_.
+
+Expansion board hardware guide
+------------------------------
+
+The document explaining the hardware details of the expansion board can be found
+`in this PDF <https://github.com/wipy/wipy/blob/master/docs/User_manual_exp_board.pdf>`_.
+
+Powering by an external power source
+------------------------------------
+
+The WiPy 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 WiPy so you
+must be careful when connecting anything to VIN.**
+
+- When powering via ``VIN``:
+
+   **The input voltage must be between 3.6V and 5.5V.**
+
+- When powering via ``3V3``:
+
+   **The input voltage must be exactly 3V3, ripple free and from a supply capable
+   of sourcing at least 300mA of current**
+
+Performing firmware upgrades
