+### Sending custom headers
+
+Sending custom headers is easy with the `withHeader()` method. Multiple calls can be chained together to add multiple headers to the request:
+
+```php
+
+    use Ixudra\Curl\Facades\Curl;
+
+    // Send a GET request to: http://www.foo.com/bar with 2 custom headers
+    $response = Curl::to('http://foo.com/bar')
+        ->withHeader('MyFirstHeader: 123')
+        ->withHeader('MySecondHeader: 456')
+        ->get();
+
+```
+
+Alternatively, you can use the `withHeaders()` to combine multiple headers into one method call:
+
+```php
+
+    use Ixudra\Curl\Facades\Curl;
+
+    // Send a GET request to: http://www.foo.com/bar with 2 custom headers
+    $response = Curl::to('http://foo.com/bar')
+        ->withHeaders( array( 'MyFirstHeader: 123', 'MySecondHeader: 456' ) )
+        ->get();
+
+```
+
+
+### Specifying the content type
+
+Sending custom headers is easy with the `withcontentType()` method. Multiple calls can be chained together to add multiple headers to the request:
+
+```php
+
+    use Ixudra\Curl\Facades\Curl;
+
+    // Send a GET request to: http://www.foo.com/bar with a json content type
+    $response = Curl::to('http://foo.com/bar')
