 ## Installation
 
-See [INSTALL.md](INSTALL.md) for complete installation instructions.
+### System Installation (Debian Package - Recommended for Raspberry Pi)
 
-### Quick Start
+The easiest way to install on Raspberry Pi OS is using the pre-built Debian package:
 
 ```bash
-# Clone repository
-git clone <repo-url> ~/sensorpajen
-cd ~/sensorpajen
+# Download the latest release
+wget https://gitea.wahlberg.se/api/v1/repos/fredrik/sensorpajen/releases/download/v2.0.0/sensorpajen_2.0.0_all.deb
 
-# Create and activate virtual environment
-python3 -m venv .venv
-source .venv/bin/activate
-
-# Install dependencies
-pip install -e .
+# Install
+sudo dpkg -i sensorpajen_2.0.0_all.deb
 
 # Configure
-cp config/sensorpajen.env.example config/sensorpajen.env
-cp config/sensors.json.example config/sensors.json
-nano config/sensorpajen.env  # Edit MQTT settings
-nano config/sensors.json     # Edit sensor MAC addresses
+sudo nano /etc/sensorpajen/sensorpajen.env  # Edit MQTT settings
+sudo systemctl restart sensorpajen
 
-# Set Bluetooth capabilities
-sudo setcap 'cap_net_raw,cap_net_admin+eip' $(readlink -f .venv/bin/python3)
-
-# Install systemd service
-mkdir -p ~/.config/systemd/user/
-cp systemd/sensorpajen.service ~/.config/systemd/user/
-systemctl --user daemon-reload
-sudo loginctl enable-linger $USER
-
-# Start service
-systemctl --user enable sensorpajen
-systemctl --user start sensorpajen
-
-# Check status
-systemctl --user status sensorpajen
-journalctl --user -u sensorpajen -f
+# View logs
+sudo journalctl -u sensorpajen -f
 ```
 
+The system package installs:
+- Application in `/opt/sensorpajen/`
+- Configuration in `/etc/sensorpajen/`
+- Runtime state in `/var/lib/sensorpajen/`
+- Systemd service (runs automatically)
+
+### Development Installation
+
+See [INSTALL.md](INSTALL.md) for complete development setup.
+
 ## Configuration
 
+### Quick Setup
+
+After installation, configure your MQTT broker and sensors:
+
+```bash
+# Edit MQTT settings
+sudo nano /etc/sensorpajen/sensorpajen.env
+
+# Restart service to apply changes
+sudo systemctl restart sensorpajen
+```
+
+### Approving Sensors (Discovery Workflow)
+
+The service automatically discovers nearby Bluetooth sensors and stores them in a pending list. You approve which ones to monitor:
+
+```bash
+# Start sensor discovery (if not already running)
+sudo systemctl start sensorpajen
+
+# Let it scan for a minute or two to discover sensors
+sleep 120
+
+# View discovered sensors and approve them
+sudo sensorpajen approve-sensors
+```
+
+The approval CLI will:
+1. Show newly discovered sensors with their current readings
+2. Ask you to approve, ignore, or skip each sensor
+3. Save approved sensors to `/etc/sensorpajen/sensors.json`
+4. Mark their status in `/var/lib/sensorpajen/discovered_sensors.json`
+
+When you approve a sensor, it's added to your configuration and the service automatically starts monitoring it.
+
