+# NetAlertX Installation Guide for Proxmox VE
+
+## Quick Start (ProxmoxVE LXC Container)
+
+To create a NetAlertX LXC container on Proxmox VE, run this command on your Proxmox host:
+
+```bash
+bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/ct/netalertx.sh)"
+```
+
+This will:
+- Create a Debian 13 LXC container
+- Install all dependencies automatically
+- Configure NetAlertX with NGINX on port 20211
+- Start the service automatically
+
+### Update Existing Installation
+
+To update an existing NetAlertX container:
+- Type ```update``` in the NetAlertX LXC Console
+- Or run this command on your Proxmox host:
+```bash
+bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/ct/netalertx.sh)" -s update
+```
+
+---
+
+## Installation Process Overview
+
+### 1. **System Preparation**
+- Updates system packages
+
+### 2. **Dependency Installation**
+- Installs NGINX web server
+- Installs Python 3 and development tools
+- Installs network scanning tools (nmap, arp-scan, fping, etc.)
+- Installs system utilities (sqlite3, dnsutils, avahi-daemon, etc.)
+
+### 3. **Application Setup**
+- Clones NetAlertX repository to `/app`
+- Creates Python virtual environment at `/opt/netalertx-env`
+- Installs Python dependencies from requirements.txt
+- Configures NGINX with default port 20211
+
+### 4. **File Structure Creation**
+- Creates persistent directories for `/app/log` and `/app/api`
+- Creates log files and plugin directories
+- Copies initial database and configuration files
+- Sets secure file permissions (www-data user/group)
+- Configures systemd RuntimeDirectory (`/run/netalertx`) for volatile service files
+
+### 5. **Service Configuration**
+- Creates startup script at `/app/start.netalertx.sh`
+- Installs systemd service (`netalertx.service`)
+- Enables auto-start on boot
+- Starts NetAlertX and NGINX services
+
+### 6. **Hardware Vendor Database**
+- Updates IEEE OUI database for MAC address vendor identification (if not present)
+
+---
+
+## Post-Installation
+
+### Accessing NetAlertX
+
+After successful installation, access the web interface at:
+
+```
+http://YOUR_SERVER_IP:YOUR_PORT
+```
+
+**Default port**: 20211
+
+To find your server IP:
+```bash
+ip -4 route get 1.1.1.1 | awk '{for(i=1;i<=NF;i++) if ($i=="src") {print $(i+1); exit}}'
+```
+
+### Service Management
+
+```bash
+# Check service status
+systemctl status netalertx.service
+
+# View real-time logs
+journalctl -u netalertx.service -f
+
+# Restart service
+systemctl restart netalertx.service
+
+# Stop service
+systemctl stop netalertx.service
+```
+
+---
+
+## Important File Locations
+
+| Component | Location |
+|-----------|----------|
+| Installation Directory | `/app` |
+| Configuration File | `/app/config/app.conf` |
+| Database File | `/app/db/app.db` |
+| NGINX Configuration | `/etc/nginx/conf.d/netalertx.conf` |
+| Web UI (symlink) | `/var/www/html/netalertx` → `/app/front` |
+| Python Virtual Env | `/opt/netalertx-env` |
+| Systemd Service | `/etc/systemd/system/netalertx.service` |
+| Startup Script | `/app/start.netalertx.sh` |
+| Application Logs | `/app/log/` (persistent) |
+| API Files | `/app/api/` (persistent) |
+| Service Runtime | `/run/netalertx/` (tmpfs, systemd-managed) |
+
+### Storage Strategy (Hybrid Approach)
+
+**Persistent Storage** (survives reboots):
+- `/app/log/app.log` - Main application log
+- `/app/log/execution_queue.log` - Task execution log
+- `/app/log/app_front.log` - Frontend log
+- `/app/log/app.php_errors.log` - PHP error log
+- `/app/log/stderr.log` - Standard error output
+- `/app/log/stdout.log` - Standard output
+- `/app/log/db_is_locked.log` - Database lock log
+- `/app/api/user_notifications.json` - User notification data
+
+**Volatile Storage** (tmpfs, cleared on reboot):
+- `/run/netalertx/` - Systemd-managed runtime directory for service temporary files
+
+Systemd service logs are always available via: `journalctl -u netalertx.service`
+
+---
+
+## Environment Variables
+
+The installation script supports the following environment variables:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `NETALERTX_ASSUME_YES` | Skip all interactive prompts | (not set) |
+| `ASSUME_YES` | Alternative to NETALERTX_ASSUME_YES | (not set) |
+| `PORT` | HTTP port for web interface | 20211 |
+| `NETALERTX_FORCE` | Force installation without prompts | (not set) |
+
+---
+
+## Security Considerations
+
+- **Runtime directory**: Systemd manages `/run/netalertx/` as tmpfs with `noexec,nosuid,nodev` flags
+- **File permissions**: Application files restricted to `www-data` user/group only (mode 0750)
+- **Service isolation**: Runs as unprivileged `www-data` user
+- **Automatic restart**: Service configured to restart on failure
+- **Persistent logs**: Application logs survive reboots for debugging and audit trails
+
+---

 ### Installation
 
-## Download and run the installer
+#### Proxmox VE Helper Script (Recommended)
+This is the easiest way to deploy NetAlertX on Proxmox. Run this command on your Proxmox host:
 ```bash
-wget https://raw.githubusercontent.com/jokob-sk/NetAlertX/refs/heads/main/install/proxmox/proxmox-install-netalertx.sh -O proxmox-install-netalertx.sh && chmod +x proxmox-install-netalertx.sh && ./proxmox-install-netalertx.sh
+bash -c "$(wget -qLO - https://github.com/netalertx/NetAlertX/raw/main/install/proxmox/ct/netalertx.sh)"
+```
+
+#### Standalone Script (Inside existing LXC/VM)
+Download and run the installer inside a fresh Debian/Ubuntu system:
+```bash
+wget https://raw.githubusercontent.com/netalertx/NetAlertX/main/install/proxmox/proxmox-install-netalertx.sh -O proxmox-install-netalertx.sh && chmod +x proxmox-install-netalertx.sh && ./proxmox-install-netalertx.sh
 ```
