+# Preparation
+
+Distribute Arduinos and parts…
+
+If you haven’t downloaded and installed the Arduino IDE, drivers (for Macs only), do that now while we are getting parts distributed. See the  AdaFruit website BlueFruit page
+If you are on a mac, you will additionally need to install the USB to UART bridge drivers provided by Silabs
+By Wednesday you will also need the Bluefruit LE Connect app, and here is the AdaFruit website describing how to install that
+
+Your circuitry kits are from amazon: https://smile.amazon.com/gp/product/B01EROKLBC
