-Orange3 Example Add-on
+Orange3 Scoring
 ======================
 
-This is an example add-on for [Orange3](http://orange.biolab.si). Add-on can extend Orange either 
-in scripting or GUI part, or in both. We here focus on the GUI part and implement a simple (empty) widget,
-register it with Orange and add a new workflow with this widget to example tutorials.
+This is an scoring/inference add-on for [Orange3](http://orange.biolab.si). This add-on adds widgets to
+load [PMML](http://dmg.org/pmml/v4-4/GeneralStructure.html) and [PFA](http://dmg.org/pfa/index.html) models 
+and score data.
