+MicroPython tutorial for ESP32
+==============================
+
+This tutorial is intended to get you started using MicroPython on the ESP32
+system-on-a-chip.  If it is your first time it is recommended to follow the
+tutorial through in the order below.  Otherwise the sections are mostly self
+contained, so feel free to skip to those that interest you.
+
+The tutorial does not assume that you know Python, but it also does not attempt
+to explain any of the details of the Python language.  Instead it provides you
+with commands that are ready to run, and hopes that you will gain a bit of
+Python knowledge along the way.  To learn more about Python itself please refer
+to `<https://www.python.org>`__.
