+# 🐳 Docker Compose Installation
+
+This folder provides standard Docker Compose configurations to get **NetAlertX** up and running quickly. This method is ideal for users on **Proxmox**, **TrueNAS Scale**, **Portainer**, or standard Linux hosts who prefer a simple, declarative setup.
+
+## 🚀 Getting Started
+
+### 1. Choose your flavor
+
+*   **Stable (Recommended):** Use `docker-compose.yml`. This tracks the latest stable release.
+*   **Development:** Use `docker-compose.dev.yml`. This tracks the `dev` branch and contains the latest features (and potential bugs).
+
+### 2. Deploy
+
+Download the chosen file to a directory on your server (e.g., `netalertx/`). You can switch between Stable and Dev versions easily by pointing to the specific file.
+
+**For Stable:**
+```bash
+docker compose -f docker-compose.yml up -d --force-recreate
+```
+
+**For Development:**
+```bash
+docker compose -f docker-compose.dev.yml up -d --force-recreate
+```
+
+> [!NOTE]
+> The `--force-recreate` flag ensures that your container is rebuilt with the latest configuration, making it seamless to switch between versions. Initial startup might take a few minutes.
+
+## ⚙️ Configuration
+
+### Storage
+By default, these files use a **Docker Named Volume** (`netalertx_data`) for persistent storage. This is the easiest way to get started and ensures data persists across upgrades.
+
+> [!TIP]
+> If you prefer to map a specific folder on your host (e.g., `/mnt/data/netalertx` on Proxmox or TrueNAS), edit the `volumes` section in the compose file to use a **bind mount** instead.
+
+### Networking
+The container uses `network_mode: host` by default. This is **required** for core features like ARP scanning (`arp-scan`) to work correctly, as the container needs direct access to the network interface to discover devices.
+
+### Environment Variables
+You can customize the application by editing the `environment` section in the compose file. Common overrides include:
+
+*   `TZ`: Timezone (mapped via `/etc/localtime`).
+*   `SCAN_SUBNETS`: Define specific subnets to scan if auto-detection fails (e.g., `192.168.1.0/24`).
+
+For a full list of environment variables and configuration options, see the [Customize with Environment Variables](https://docs.netalertx.com/DOCKER_COMPOSE/?h=environmental+variables#customize-with-environmental-variables) section in the documentation.
