+Transformations are performed by Transformation Services which are available as [transformation add-ons](/addons/#transform).
+The relevant add-on needs to be installed via the Main UI or addons.cfg before use.

 ## Usage
 
 Transformations are applicable in Item and Sitemap element labels and inside DSL rules.
