## Building App from scratch
Step by step to create a new app from scratch
1.	Build simple Requirements doc
2.	Extract Use Cases from Requirements Doc
3.	Find Use Case Dependencies.  i.e. use case 5 cannot be done until 2 is complete…
4.	Order Use Cases. Start with the most essential use case that has no dependencies.
5.	Find all Core use cases. i.e. Adds to the structure of the app and adds data to app. Then find supporting use cases to implement to test…
Sketch out User experience. i.e. what will the site look like…

or enter... to cmd...
