+### 3\. (Optional but Recommended) Set up a Local DNS Caching Resolver
 
-  * Flask\>=2.3.3
+Running a local DNS caching resolver can significantly speed up DNS queries and reduce your network footprint. Here’s how to set up `unbound` on a Debian-based Linux distribution (like Ubuntu).

-## Configuration

-DNSRecon is configured using a `.env` file. You can copy the provided example file and edit it to suit your needs:
 
 ```bash
-cp .env.example .env
+sudo apt update
+sudo apt install unbound -y
 ```
 
-The following environment variables are available for configuration:
+**b. Configure Unbound:**
+Create a new configuration file for DNSRecon:
 
-| Variable | Description | Default |
+```bash
-| :--- | :--- | :--- |
+sudo nano /etc/unbound/unbound.conf.d/dnsrecon.conf
-| `SHODAN_API_KEY` | Your Shodan API key. | |
+```
-| `FLASK_SECRET_KEY`| A strong, random secret key for session security. | `your-very-secret-and-random-key-here` |
-| `FLASK_HOST` | The host address for the Flask application. | `127.0.0.1` |
-| `FLASK_PORT` | The port for the Flask application. | `5000` |
-| `FLASK_DEBUG` | Enable or disable Flask's debug mode. | `True` |
-| `FLASK_PERMANENT_SESSION_LIFETIME_HOURS`| How long a user's session in the browser lasts (in hours). | `2` |
-| `SESSION_TIMEOUT_MINUTES` | How long inactive scanner data is stored in Redis (in minutes). | `60` |
-| `DEFAULT_RECURSION_DEPTH` | The default number of levels to recurse when scanning. | `2` |
-| `DEFAULT_TIMEOUT` | Default timeout for provider API requests in seconds. | `30` |
-| `MAX_CONCURRENT_REQUESTS`| The number of concurrent provider requests to make. | `5` |
-| `LARGE_ENTITY_THRESHOLD`| The number of results from a provider that triggers the "large entity" grouping. | `100` |
-| `MAX_RETRIES_PER_TARGET`| The number of times to retry a target if a provider fails. | `8` |
-| `CACHE_EXPIRY_HOURS`| How long cached provider responses are stored (in hours). | `12` |

+Add the following content to the file:
 
-## Systemd Service
+```
+server:
+    # Listen on localhost for all users
+    interface: 127.0.0.1
+    access-control: 0.0.0.0/0 refuse
+    access-control: 127.0.0.0/8 allow
+
+    # Enable prefetching of popular items
+    prefetch: yes
+```
+
+**c. Restart Unbound and set it as the default resolver:**
+
+```bash
+sudo systemctl restart unbound
+sudo systemctl enable unbound
+```
+
+To use this resolver for your system, you may need to update your network settings to point to `127.0.0.1` as your DNS server.
+
+**d. Update DNSProvider to use the local resolver:**
+In `dnsrecon/providers/dns_provider.py`, you can explicitly set the resolver's nameservers in the `__init__` method:
+
+```python
+# dnsrecon/providers/dns_provider.py
+
+class DNSProvider(BaseProvider):
+    def __init__(self, session_config=None):
+        """Initialize DNS provider with session-specific configuration."""
+        super().__init__(...)
+
+        # Configure DNS resolver
+        self.resolver = dns.resolver.Resolver()
+        self.resolver.nameservers = ['127.0.0.1'] # Use local caching resolver
+        self.resolver.timeout = 5
+        self.resolver.lifetime = 10
+```
+
+## Usage (Development)
+
+### 1\. Start the Application
+
+```bash
+python app.py
+```
+
+### 2\. Open Your Browser
+
+Navigate to `http://127.0.0.1:5000`.
+
+### 3\. Basic Reconnaissance Workflow
+
+1.  **Enter Target Domain**: Input a domain like `example.com`.
+2.  **Select Recursion Depth**: Depth 2 is recommended for most investigations.
+3.  **Start Reconnaissance**: Click "Start Reconnaissance" to begin.
+4.  **Monitor Progress**: Watch the real-time graph build as relationships are discovered.
+5.  **Analyze and Export**: Interact with the graph and download the results when the scan is complete.
+
+## Production Deployment
+
+To deploy DNSRecon in a production environment, follow these steps:
+
+### 1\. Use a Production WSGI Server
+
+Do not use the built-in Flask development server for production. Use a WSGI server like **Gunicorn**:
+
+```bash
+pip install gunicorn
+gunicorn --workers 4 --bind 0.0.0.0:5000 app:app
+```
+
+### 2\. Configure Environment Variables
+
+Set the following environment variables for a secure and configurable deployment:
+
+```bash
+# Generate a strong, random secret key
+export SECRET_KEY='your-super-secret-and-random-key'
+
+# Set Flask to production mode
+export FLASK_ENV='production'
+export FLASK_DEBUG=False
+
+# API keys (optional, but recommended for full functionality)
+export SHODAN_API_KEY="your_shodan_key"
+```
+
+### 3\. Use a Reverse Proxy
+
+Set up a reverse proxy like **Nginx** to sit in front of the Gunicorn server. This provides several benefits, including:
+
+  - **TLS/SSL Termination**: Securely handle HTTPS traffic.
+  - **Load Balancing**: Distribute traffic across multiple application instances.
+  - **Serving Static Files**: Efficiently serve CSS and JavaScript files.
+
+**Example Nginx Configuration:**
+
+```nginx
+server {
+    listen 80;
+    server_name your_domain.com;
+
+    location / {
+        return 301 https://$host$request_uri;
+    }
+}
+
+server {
+    listen 443 ssl;
+    server_name your_domain.com;
+
+    # SSL cert configuration
+    ssl_certificate /etc/letsencrypt/live/your_domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your_domain.com/privkey.pem;
+
+    location / {
+        proxy_pass http://127.0.0.1:5000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    }
+
+    location /static {
+        alias /path/to/your/dnsrecon/static;
+        expires 30d;
+    }
+}
+```
+
+## Autostart with systemd
 
 To run DNSRecon as a service that starts automatically on boot, you can use `systemd`.

 ```
 
------
+## Security Considerations
+
+  - **API Keys**: API keys are stored in memory for the duration of a user session and are not written to disk.
+  - **Rate Limiting**: DNSRecon includes built-in rate limiting to be respectful to data sources.
+  - **Local Use**: The application is designed for local or trusted network use and does not have built-in authentication. **Do not expose it directly to the internet without proper security controls.**
