-## Quick Deploy (New Pi)
+## 🚀 One-Command Installation (Recommended)
+
+**Just run this on your Pi Zero 2:**
+
 ```bash
-git clone <your-gitea-repo>
-cd record-player-sonos-aux
+curl -fsSL https://git.geertrademakers.nl/master/sonos-aux-recordplayer-pi/raw/branch/master/install.sh | bash
+```
+
+Or with wget:
+```bash
+wget -qO- https://git.geertrademakers.nl/master/sonos-aux-recordplayer-pi/raw/branch/master/install.sh | bash
+```
+
+**What it does:**
+- ✅ Installs all prerequisites (darkice, icecast2, alsa-utils)
+- ✅ Clones/updates the repository
+- ✅ Configures USB audio as card 0 (fixes disconnections!)
+- ✅ Deploys all files and systemd service
+- ✅ Sets up Icecast2
+- ✅ Enables auto-start on boot
+
+**After installation:**
+1. Edit config: `nano /home/pi/darkice.cfg` (change password!)
+2. Reboot: `sudo reboot`
+3. Verify: `journalctl -u sonos-aux.service -f`
+
+---
+
+## Quick Deploy (Manual - Alternative Method)
+```bash
+git clone https://git.geertrademakers.nl/master/sonos-aux-recordplayer-pi.git
+cd sonos-aux-recordplayer-pi
 chmod +x *.sh
-sudo ./02-deploy.sh
+sudo ./install.sh
 ```

+## 🔧 Stability Fixes (Recommended for 24/7)
+
+Raspberry Pi Zero W/2W often loses WiFi due to power management. These steps ensure rock-solid uptime.
+
+### 1. Disable WiFi PowerSave (systemd service)
+
+```bash
+sudo nano /etc/systemd/system/wifi-powermanagement-off.service
+```
+
+```ini
+[Unit]
+Description=Disable WiFi Power Management
+After=network.target
+
+[Service]
+Type=oneshot
+ExecStart=/sbin/iwconfig wlan0 power off
+RemainAfterExit=yes
+
+[Install]
+WantedBy=multi-user.target
+```
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable wifi-powermanagement-off
+sudo systemctl start wifi-powermanagement-off
+```
+
+**Verify:** `iwconfig` should show `Power Management:off` [web:27][web:28]
+
+### 2. Hardware Watchdog (Network + Load Monitoring)
+
+```bash
+sudo apt install watchdog -y
+sudo nano /etc/watchdog.conf
+```
+
+**Replace with this optimal config:**
+```ini
+watchdog-device = /dev/watchdog
+interval = 20
+retry-timeout = 180
+ping = 192.168.1.1    # Your UniFi gateway
+ping = 1.1.1.1        # Cloudflare backup
+ping-count = 3
+realtime = yes
+priority = 50
+max-load-1 = 24
+max-load-5 = 0
+max-load-15 = 0
+```
+
+```bash
+sudo systemctl enable watchdog
+sudo systemctl start watchdog
+```
+
+**Test safely:** `sudo systemctl status watchdog` + `sudo journalctl -u watchdog -f`
+
+### 3. Verify Everything
+
+After reboot:
+```bash
+iwconfig           # Power Management:off
+systemctl status watchdog  # active (running)
+journalctl -u watchdog -n20  # Recent heartbeats
+```
+
+This combo prevents WiFi dropouts + auto-recovers from hangs/freezes while keeping your Sonos AUX stream running 24/7.
