+# Tor Detector PHP library
 A library to detect if your website visitor is from a TOR network or not. 
 
 At the moment this is achieved by using a DNS lookup method as described in https://trac.torproject.org/projects/tor/wiki/doc/TorDNSExitList
 
-# Credit
+## Usage
+
+```php
+$tor_detector = new OnlineSid\Tor\TorDetector();
+
+$your_server_ip = '1.2.3.4'; // the IP address of your server (web server)
+$user_ip = '62.102.148.67'; // is this IP from TOR exit node?
+
+if ($tor_detector->check($user_ip, 80, $your_server_ip)) {
+    echo "Tor!\n";
+} else {
+    echo "Not TOR!\n";
+}
+```
