 Creating custom responses
 ^^^^^^^^^^^^^^^^^^^^^^^^^
 
+If no premade Response fits the needed use case, it is possible to extend the Response base class and custom Response. The only thing that needs to be implemented is the **render** method which returns the result as string.
+
+Creating a custom XMLResponse class could look like this:
+
+.. code-block:: php
+
+    <?php
+    namespace OCA\MyApp\Http;
+
+    use OCP\AppFramework\Http\Response;
+
+    class XMLResponse extends Response {
+
+        private array $xml;
+
+        public function __construct(array $xml) {
+            $this->addHeader('Content-Type', 'application/xml');
+            $this->xml = $xml;
+        }
+
+        public function render(): string {
+            $root = new SimpleXMLElement('<root/>');
