 This repository is primarily a collection of resources and learning aides for Steve's classroom work. This can include coding examples in various languages, project examples, documentation, instructional guides, and just about anything else.
 
+## Prerequesits
+
+* The requests module provides web/REST API access
+* The colorama module provides access to color and cursor positioning in a terminal
+
+Inside a terminal:
+```bash
+pip install requests colorama

 ## [Python Basics](Python/)
 
 This is the home of many examples of basic Python syntax and logic. An attempt has been made to name them in such a way that they increase in complexity and build on each other as you go down the list of files.
