 ## Outline of the tutorial
-The tutorial will take you through stages to go a from a script (stage 0) to

-portions of the differences between each stages but each of them is provided as 
-a separate folder are provided to make sure everyone to get to the end point:
+The tutorial will guide you through all the stages from a basic python script 
+(stage 0) to a fully packaged and installable application (stage 8). The 
+included exercises will walk you through developing the primary product of 
+each stage. 
+A solution is available for each exercise, though, to ensure all participants 
+are able to reach the end goal.
