-* Raspberry Pi Zero W (low power, small, Wifi built in)
+> Note only the Pi Zero W and recent Pi's support the USB protocol for connecting to them as network devices. Not needed for normal operation, but it's very helpful during the setup process.

+## Basic Steps
 
-## Short Instructions for connecting to Raspberry Pi Zero W (or similar) over USB (no HDMI needed)
+This is captured in the original Reddit post, but starting to recreate this here so the community can contribute to the scripts and setup instructions. 
 
-* [Gist showing example steps](https://gist.github.com/gbaman/975e2db164b3ca2b51ae11e45e8fd40a)
+1. Obtain the necessary hardware (Pi, USB cable, USB splitter if needed, SD card)
+2. [Download Raspbian Stretch Lite](https://www.raspberrypi.org/downloads/raspbian/) (tested by original poster, others may work). 
+3. Write the Raspbian image to the SD card. [Etcher (etcher.io)](https://etcher.io/) works well and is multi-platform.
+4. If you don't have a keyboard/HDMI setup to boot the Pi and edit/transfer files directly, you'll probably want to connect to it over USB. See the section below for instructions there. 
+5. Create the network destination for your Dashcam files. The original post uses a Windows share, but hopefully this repo will get updated to support other destinations.
+6. Continue to follow the instructions in the Reddit post; this readme will be updated with full instructions over time. 
+
+## Connecting to Raspberry Pi Zero W (or similar) over USB (no HDMI needed)
+
+Basically what you're doing is using the Pi's capability to emulate a network connection over USB. So you need to get the Pi (the guest) set up to load the proper modules to do so, and then connect from your machine (the host) using a shell (like iTerm+SSH on macOS, or PuTTY on Windows). 
+
+Here are a few ways to accomplish this

+* [Script to setup the Pi for connecting over USB](https://github.com/BigNate1234/rpi-USBSSH)
+   * (I.e. First write the OS image to the SD card, then this script will make the changes to the card so you can boot it and access it over the USB cable. 
+   * **Assumes the SD card for the Pi is mounted at /Volumes/boot , and that you can use `sh`/`bash`**. This _should_ be the default for a Mac; if using something else, modify the script accordingly.
