+![Request-Response Cycle](img/Lab-07-request-response-cycle.png)
+![Functions Overview](img/lab-07%20functions%20overview.png)
+
+## Getting Started
+<!-- What are the steps that a user must take in order to build this app on their own machine and get it running? -->
+
+## Architecture
+<!-- Provide a detailed description of the application design. What technologies (languages, libraries, etc) you're using, and any other relevant design information. -->
+
+## Change Log
+<!-- Use this area to document the iterative changes made to your application as each feature is successfully implemented. Use time stamps. Here's an example:
+
+01-01-2001 4:59pm - Application now has a fully-functional express server, with a GET route for the location resource. -->
+
+## Credit and Collaborations
+<!-- Give credit (and a link) to other people or resources that helped you build this application. -->
