+## Installing
+
+First make sure that your Circuit Playground Express has the
+[latest version of CircuitPython installed](https://circuitpython.org/board/adafruit_macropad_rp2040/).
+See [https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-quickstart](https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-quickstart)
+for instructions on how to update the Circuit Playground Express to have the latest version of
+CircuitPython.
+
+When installing the Busy/Free Indicator for the first time, extract the latest
+[CIRCUITPY.ZIP](https://github.com/deckerego/busy-free_indicator/releases/latest)
+into a directory, then copy the contents of that extracted archive
+into the CIRCUITPY drive that appears when you plug in your Circuit Playground Express.
+Ensure that the contents of the `lib/` subdirectory are also copied - these are
+the precompiled Adafruit libraries that power the Playground Express.
