 1. Either clone the repository and build software locally, fork the repository and run the Github Actions build, or download the latest commit build.
 2. Uncompress the built zip file and burn this to an SD card. We recommend using [Raspberry Pi Imager](https://www.raspberrypi.com/software/) for this.
+3. Alternatively, flash the latest Raspberry Pi OS (Lite) image to an SD card and then follow the steps in [README_RASPBIAN_INSTALL.md](README_RASPBIAN_INSTALL.md) to install the software manually.

+# Installing on Raspbian / Raspberry Pi OS Lite
+
+On a fresh install of Raspberry Pi OS Lite (formerly Raspbian Lite), you can
+install the Naturewatch Camera Server software by following these steps. One
+advantage to using this method is that you can take advantage of the latest
+Raspberry Pi OS updates and features, and you can customize the installation in
+Raspberry Pi Imager before flashing the SD card (for example, enabling SSH on
+first boot).
+
+## On your Raspberry Pi
+
+### Update and install necessary packages:
+
+```bash
+sudo apt-get update
+sudo apt-get upgrade -y
+sudo apt-get install -y coreutils p7zip-full qemu-user-static python3-git python3-picamera2 git python3-pip python3-libcamera libcap-dev ffmpeg python3-flask python3-numpy python3-opencv python3-kms++
+```
+
+### Clone the Naturewatch Camera Server repository
+
+```bash
+cd /home/pi
+git clone https://github.com/interactionresearchstudio/NaturewatchCameraServer-CommunityDevelopmentEdition.git NaturewatchCameraServer
+```
+
+### Copy the frontend build files
+
+Run `build_node_app.sh` on your main machine and copy the `build` folder to the
+Pi, to `/home/pi/NaturewatchCameraServer/naturewatch_camera_server/static/client/build`. Or you can
+download the build folder from a GH workflow run. Once you have the build folder
+in place, continue here:
+
+### Set up the Python virtual environment and install dependencies
+
+```bash
+cd /home/pi/NaturewatchCameraServer
+python -m venv --system-site-packages /home/pi/NaturewatchCameraServer/.venv
+/home/pi/NaturewatchCameraServer/.venv/bin/pip install -r requirements.txt
+```
+
+### Set up the service
+
+Uncomment the commented lines to enable WiFi hotspot.
+
+```bash
+cd /home/pi/NaturewatchCameraServer
+export DIR=$(pwd)
+TEMPLATES="${DIR}/helpers"
+sed -e "s|\${path}|/home/pi|g" "${TEMPLATES}/python.naturewatch.service" > "./python.naturewatch.service"
+# sed -e "s|\${path}|/home/pi|g" "${TEMPLATES}/wifisetup.service" > "./wifisetup.service"
+sudo cp python.naturewatch.service "/etc/systemd/system/"
+sudo chmod 644 /etc/systemd/system/python.naturewatch.service
+# sudo chmod 644 /etc/systemd/system/wifisetup.service
+sudo systemctl daemon-reload
+sudo systemctl enable python.naturewatch.service
+# sudo systemctl enable wifisetup.service
+sudo systemctl start python.naturewatch.service
+# systemctl start wifisetup.service
+(sudo crontab -l 2>/dev/null; echo "# Start watchdog script at boot time") | sudo crontab -
+(sudo crontab -l 2>/dev/null; echo "@reboot ${TEMPLATES}/watchdog.sh > /dev/null 2>&1") | sudo crontab -
+
+sudo systemctl status python.naturewatch.service
