+# Unraid Installation Guide for PNGer
+
+This guide walks you through installing PNGer on Unraid using the Docker tab and "Add Container" feature.
+
+## Requirements
+- Unraid OS with Docker enabled.
+- Appdata path ready (optional, if you want persistent temp storage).
+
+## Step-by-Step Installation
+
+1. Log into your Unraid WebGUI and navigate to the **Docker** tab.
+2. Scroll to the bottom and click on **Add Container**.
+3. Fill in the following details:
+   - **Name**: `PNGer`
+   - **Repository**: `jason/pnger:latest` (or the repository you pushed the image to, e.g., `ghcr.io/yourusername/pnger:latest` if hosted, or `pnger:latest` if built locally).
+   - **Network Type**: `Bridge`
+
+4. Click on **+ Add another Path, Port, Variable, Label or Device** to add the required parameters.
+
+### Port Configuration
+- **Config Type**: `Port`
+- **Name**: `WebUI`
+- **Container Port**: `3000`
+- **Host Port**: `8080` (or whichever port is free on your Unraid system).
+- **Connection Protocol**: `TCP`
+
+### Environment Variables
+Add the following variables by clicking **+ Add another Path, Port, Variable...** and selecting **Variable** as the Config Type:
+
+1. **PUID**
+   - **Name**: `User ID (PUID)`
+   - **Key**: `PUID`
+   - **Value**: `99` (Unraid's nobody user).
+
+2. **PGID**
+   - **Name**: `Group ID (PGID)`
+   - **Key**: `PGID`
+   - **Value**: `100` (Unraid's users group).
+
+3. **TZ**
+   - **Name**: `Timezone`
+   - **Key**: `TZ`
+   - **Value**: `America/New_York` (Enter your specific Timezone here).
+
+4. **MAX_FILE_SIZE** (Optional)
+   - **Name**: `Max Upload Size (Bytes)`
+   - **Key**: `MAX_FILE_SIZE`
+   - **Value**: `10485760` (Default is 10MB; 10485760 bytes).
+
+### Volume Mapping (Optional)
+If you require persistence for the temporary directory processing uploads (usually not required):
+- **Config Type**: `Path`
+- **Name**: `Temp Processing Dir`
+- **Container Path**: `/app/temp`
+- **Host Path**: `/mnt/user/appdata/pnger/temp`
+
+5. **Apply Settings**:
+   - Scroll to the bottom and press **Apply**. Unraid will pull the image and create the container with the specified settings.
+
+## Accessing PNGer
+Once the container states "started", you can access the Web GUI by navigating to your Unraid IP and the port you assigned (e.g., `http://192.168.1.100:8080`).
+
+---
+
+**Troubleshooting:**
+If the container stops instantly, check the **Logs** in Unraid. Ensure that the port you selected on the host is not already in use by another container (like a web server or another app).
