+# Implementing for Maintainability - Demo for Refactoring
+
+This project is about refactoring an ugly method of the famous CocktailPro. The CocktailPro is a software controlled machine that mixes cocktails (e.g. the Caipirinha). It uses recipes of cocktails and available ingredients to find out what cocktails can be mixed. This is done by the method *pruefeRezepte()* which is quite a mess.
+
+You are supposed to clean up the method by using refactorings.
+
+Enjoy
