+Installing Python 3.6 under Ubuntu
+----------------------------------
+
+Many Ubuntu distributions have an incompatible Python version baked in.
+Because of this, it is easier to install Python 3.6 rather than attempting
+to update Python 3.5.2 to 3.5.3.  See `contrib/python3.6/python-3.6.sh`_.
+
+
+Installing on Raspberry Pi 3
+----------------------------
+
+To install on the Raspberry Pi 3 you will need to update to the "stretch" distribution. 
+See the full procedure in `contrib/raspberrypi3/install_electrumx.sh`_.
+
+See also `contrib/raspberrypi3/run_electrumx.sh`_ for an easy way to configure and 
+launch electrumx.
