-IoT Mini Project - 2024
+# IoT Mini Project - 2024
+
+This mini project uses picamera to detect motion, upon detecting motion, it sends notification to devices subscribed to the channel using ntfy.sh
 
 ---
+
+## Prerequisites:
+1. Raspberry Pi (only tested on 3B+, should work on 2/4/5 as well)
+2. Pi Camera
+3. Internet connection
+4. Raspberry Pi OS **64-bit**
+
+> [!IMPORTANT]
+> USE 64-BIT OS FOR FASTER PROCESSING.
+
+## Steps to setup
+
+1. Clone this repository:
+```shell
+git clone https://git.kska.io/notkshitij/iot-mini.git
+```
+
+2. Change current working directory:
+```shell
+cd ./iot-mini
+```
+
+3. Run `setup.sh`:
+```shell
+./setup.sh
+```
+
+
+4. Setup firewall on Raspberry Pi:
+```shell
+sudo apt install -y ufw
+sudo ufw default allow outgoing
+sudo ufw default deny incoming
+sudo ufw allow 22 # for ssh
+sudo ufw allow 80 # for ntfy
+sudo ufw allow 51821/tcp # wireguard tcp
+sudo ufw allow 51820/udp # wireguard udp
+sudo ufw status numbered
+sudo ufw enable
+sudo systemctl start ufw
+sudo systemctl enable ufw
+```
+
+5. Setup Wireguard:
+    - Generate bcrypt password hash by running:
+    ```shell
+    docker run -it ghcr.io/wg-easy/wg-easy wgpw <PASSWORD-HERE>
+    ```
+
+    This will return a `PASSWORD_HASH`
+
+    - Create a file in the current directory called `.env`
+
+    - Add the following values in `.env` file:
+    ```env
+    PASS='<PASSWORD_HASH generated here>'
+    IP=<PUBLIC IP>
+
+    # Inside single quotations, paste the password hash for PASS variable
+    # Get your public IP by using something like http://ip.me, and paste your public IP there
+    ```
+
+8. Create and run the containers:
+```shell
+docker compose up -d
+```
+
+9. Check if ntfy.sh is setup correctly:
+    - Visit `<RASPBERRYPI-IP>:80` from a browser. Make sure Raspberry Pi and the other device are on the same network. On Raspberry Pi, you can visit `localhost:8080`
+    - If you see a dashboard, it implies Docker and ntfy.sh were setup correctly.
+
+10. In ntfy.sh dashboard, in the left menu at the bottom, click on `Subscribe to topic`, and specify the topic name: `motion-sensing`
+
+> [!NOTE]
+> Make sure you're in the directory where you cloned this repo while running all these commands.
