 This is an example that shows the basics of how to create CRUD screens with NodeJS using ExpressJS and MySQL. CRUD stands for Create, Read, Update and Delete - this is the bread and butter of web application development.
 
+The app is deployed at [https://codex-basic-express-app.herokuapp.com/](https://codex-basic-express-app.herokuapp.com/).

 You use CRUD to manage all the data in your web application. Once data is stored it can be retrieved, updated, deleted or whatever your demanding client wants.
 
 I kept this example simple on purpose, but it can be used as the base of something much more complicated.
