 ### Get a shell on the Pi
-> Regardless of which way you use to access the Pi (Keyboard+HDMI or USB networking), **before you boot the Pi for for the first time with the MicroSD inserted**, verify that the /boot/cmdline.txt file on the MicroSD does not contain the parameter "init=/usr/lib/raspi-config/init_resize.sh". Delete that entire string if present.
+If you used a Windows computer to flash the OS onto the MicroSD card, follow these [Instructions](GetShellWithoutMonitorOnWindows.md).
+If you used a Mac or a Linux computer, follow these [Instructions](GetShellWithoutMonitorOnLinux.md).
 
-#### Use a monitor/keyboard/mouse 
+### Set up the USB storage functionality
-If you have a monitor with an HDMI input, a Mini HDMI to HDMI cable, a USB keyboard and a Micro USB power cable you can hook up the devices to the Pi and configure it directly. 
-1. Insert the MicroSD card into the Pi.
-1. Connect the keyboard, and monitor to the Pi.
-1. Connect the power supply to the Pi using the port labeld "PWR" on the circuitboard.
-1. When you're prompted for the password for the user "pi" use "raspberry" without the quotes.
-1. Now skip to section below titled "Get the scripts onto the Pi".
 
-#### Windows (Setup USB Networking)
+Now that you have Wifi up and running, it's time to set up the USB storage and scripts that will manage the dashcam and (optionally) music storage.
-
-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 the Pi over Wifi or USB networking. 
-* Follow [these instructions](GetShellWithoutMonitorOnWindows.md), then skip down to the section titled **Set up Set up Wifi on the Pi (manually)y**. 
-
-#### macOS or Linux (Setup Wifi or USB Networking)
-* Follow [these instructions](GetShellWithoutMonitorOnLinux.md), then proceed to the section **Set up the USB Storage Functionality**.

-
-### Set up Wifi on the Pi (manually)
-
-If you don't yet have Wifi running from the previous section, use these instructions to get it set up. Otherwise, skip to **Set up the USB Storage Functionality**.
-
-Now that you have an `ssh` shell on the Pi over USB networking, you can set up Wifi and continue with setup. 
-
-1. Enter the following commands:
-    ```
-    sudo -i
-    nano /etc/wpa_supplicant/wpa_supplicant.conf
-    ```
-1. Add this block to the bottom of the file specifying the actual SSID of your network and your actual PSK, keeping the quotes around both values. Note that the SSID may be case-sensitive on your network.
-    ```
-    network={
-      ssid="SSID"
-      psk="PASSWORD"
-    }
-    ```
-1. Press Control-O, Enter to save the file.
-1. Press Control-X to return to the command line.
-1. Configure the wifi to ensure that your Pi has access to your network.
-    ```
-    wpa_cli -i wlan0 reconfigure
-    ```
-1. Run this command
-    ```
-    ifconfig wlan0
-    ```
-1. Verify that there's an IP address on your subnet assigned. If you don't see the IP address wait for a couple of seconds and re-run the command.
