+### XML Namespace
+
+If you want to prefix all your inky tags with an XML namespace
+you can set this prefix either in constructor or via setter:
+
+```php
+use Hampe\Inky\Inky;
+
+// Constructor way
+$inky = new Inky(12, [], 'inky');
+
+// Setter way
+$inky2 = new Inky();
+$inky2->setXmlNamespace('inky');
+```
+If you declare your namespace, create a XSD and make
+it know to your IDE you can benefit from autocompletion and 
+validation features of your IDE. Your inky templates might look as
+follows:
+
+```xml
+<inky:container>
+    <inky:row class="my-row">
+        <inky:columns large="6" small="4">
+            ...
+        </inky:columns>
+    </inky:row>
+</inky:container>
+```
