+Scripts and documentation for setting up a Raspberry Pi (Zero W 1 or 2) for use in Mechatronics 1 or Cyberphysical Systems.  This single-board Linux computer is equivalent in power to the Raspberry Pi 2 but in a smaller form factor, includes WiFi and Bluetooth, and is very affordable at 15USD.  For operations that need higher computing power, we recommend the Raspberry Pi 3 or 4 which can be purchased later.

-We don't have many monitors and keyboards in V207 for students to use, so we will need to get the Raspberry Pi installed without them.

 # Using the Imager to setup a Pi Zero with ssh and Raspberry Pi Connect
+We don't have many monitors and keyboards in V207 for students to use, so we will need to get the Raspberry Pi installed without them.  This is sometimes called "headless" because we think of the monitor as a sort of head.
 
+## Creating an image
 1. Download the [Raspberry Pi Imager](https://www.raspberrypi.com/software/) and install it
     - Important note2026-06-28  The Raspberry Pi Imager 2.0.10 may have buttons with gibberish text, a [known problem](https://github.com/raspberrypi/rpi-imager/issues/1648).  The 2.0.9 image doesn't have this problem and can be [downloaded from the github distribution website](https://github.com/raspberrypi/rpi-imager/releases/tag/v2.0.9).
 1. Start the Imager program and pick your device
