This commit adds a new script `run.sh` that handles the network configuration and directory setup for Pterodactyl Wings. The key changes include:

- Checks if a UUID argument is provided and exits with an error if not
- Implements functions to check if a subnet is in use, find an available subnet, and get the gateway for a subnet
- Creates the `pterodactyl_nw` Docker network with the available subnet and gateway
- Creates the required directories for Pterodactyl (/var/lib/pterodactyl/volumes, /tmp/pterodactyl, /etc/pterodactyl, /var/log/pterodactyl)
- Sets the appropriate ownership for the created directories
- Restarts the `pterodactyl-wings` container to apply the changes

This script simplifies the setup process for Pterodactyl Wings and helps ensure the network configuration and directory structure are properly set up.

+# Setup Pterodactyl Wings
+
+This script helps set up the network configuration and directories required for Pterodactyl Wings. It handles network conflict resolution, proper directory permissions, and container management automatically.
+
+## Prerequisites
+
+- Docker installed and running
+- Root/sudo access
+- wget installed
+
+## Usage
+
+You can run the script directly using wget:
+
+```bash
+bash -c "$(wget -qLO - https://raw.githubusercontent.com/bigbeartechworld/big-bear-scripts/master/setup-pterodactyl-wings/run.sh)" -- <uuid>
+```
+
+Replace `<uuid>` with your server's UUID from the Pterodactyl panel.
+
+Example:
+
+```bash
+bash -c "$(wget -qLO - https://raw.githubusercontent.com/bigbeartechworld/big-bear-scripts/master/setup-pterodactyl-wings/run.sh)" -- 123e4567-e89b-12d3-a456-426614174000
+```
+
+## What the Script Does
+
+1. Creates required Pterodactyl directories with proper permissions
+2. Sets up Docker network `pterodactyl_nw` with proper IPv4/IPv6 configuration
+3. Automatically resolves network conflicts:
+   - Detects conflicting Docker networks
+   - Removes unused conflicting networks
+   - Provides clear instructions if manual intervention is needed
+4. Restarts the pterodactyl-wings container to apply changes
+
+## Network Configuration
+
+The script automatically creates a Docker network with the following specifications:
+
+- Network name: `pterodactyl_nw`
+- IPv4 subnet: Automatically selected from available ranges (172.40-47.0.0/16)
+- IPv4 gateway: Automatically configured based on selected subnet
+- IPv6 subnet: fd00::/64
+- IPv6 gateway: fd00::1
+- Bridge name: pterodactyl0
+
+The script intelligently:
+1. Checks existing Docker networks and system routes for conflicts
+2. Automatically selects an available subnet from a predefined list of private ranges
+3. Reconfigures the network if conflicts are detected
+4. Provides clear status messages during the setup process
+
+## Troubleshooting
+
+If you encounter issues, the script will provide clear error messages and instructions:
+
+1. Network Configuration Issues:
+   - The script will automatically try different subnet ranges
+   - Clear messages show which subnet is being used
+   - Detailed error messages if network creation fails
+
+2. Container Restart Issues:
+   - If the pterodactyl-wings container fails to restart, you'll get instructions for manual restart
+   - Use `docker restart pterodactyl-wings` if needed
+
+Common error messages and solutions:
+
+- "Could not find available subnet": All predefined subnets are in use, contact support
+- "Failed to create network": Check Docker logs and ensure Docker is running properly
+- "Failed to restart pterodactyl-wings container": Ensure the container exists and try restarting manually
+
