+===
+This is the day 7 lab with Code Fellows. The purpose of the lab is to teach students to use vanilla HTTP requests to create a server.
+
+# Modules
+Description of exported values of each module defined in lib/ directory, along with airity and expected input/return values.
+### Server.js
+Houses the code for the server. It exports an object with start and stop methods which either starts or stops the server. Currently only start is being invoked in index.js.
+* #### start
+    * Has an arity of two, which takes in a port number and callback function. Port number is preset to 3000 and the callback is a success function which logs to the server which port the server is running on.
+* #### stop
+    * Has an arity of one, which takes in a callback function. Currently not being utilized.    
+### request-parser.js
+Exports a function with an arity of one, that takes in a request and returns a new promise. It parses the data depending if its a GET or POST request.
