+# PlantUML
+This UML refactoring exercise is aimed at less technical people like analysts, testsers and other non-programmers. The key takeaway message is clarifying the need for continuous refactoring to people who do not code on a daily basis.
+
+## Running and rendering
+Several alternatives are available to render PlantUML, see https://plantuml.com/running.
+
+## Syntax
+For the syntax of activity diagrams in PlantUML, please refer to https://plantuml.com/activity-diagram-beta
+
+# Exercise
+You can find the original GildedRose challenge in the gilded-rose.puml file.
+
+If you want to illustrate how this activity diagram got to this state, you can show the requirements and the files under the /history directory. These individual files show the evolution of the activity diagram.
