-# node_express_app
-A simple node and express app with ES6 features to get you started in modern web development and practice. 
+Developed for CreativeBitStudio by our very own full stack developer Daniel C.
+
+
+Welcome to another CreativeBitStudio tutorial.
+An express-node app with Pug.
+
+This app contains all the necessary modules to develop a simple express app to play around and test with. All the way to installing the express-generator to publish a fully functional web application.  
+
+Technologies used
+
+Express 4.0
+Npm 4.1.1
+Node 6.9.0
+Pug 2.0.0 beta (can be downgraded to 2.0.0, simply) 
+
+List of all dependencies are shown in the package.json file 
+
+Nodemon is saved under development dependencies and is used to restart the server automatically anytime a change is made to the application. To start the server, simply type the command: nodemon app. 
+
+Note: each file is commented explaining what each piece of code does. 
+
+ENJOY!!
