Initial Commit

Contains a (very) basic, working Todo List Application. You can add tasks, mark them complete, and mark them incomplete. Functionality such as deleting is not yet implemented. Basic functionality is tested, though styling of error message communication is pending.

 # Todo List Example App
+
+This project is intended to be a hands-on demonstration of ways that you can
+integrate a Ruby on Rails application with Amazon Web Services. Starting from a
+simple example web application, we will show you how it can take advantage of
+various AWS offerings. We hope that this will be useful to you as you integrate
+your own applications with AWS.
+
+## The Application
+
+The application itself is not complicated - it is a simple Todo List web site,
+where you can create tasks, edit details about them, and update their status.
+
+While some additional functionality may be added over time to make the example
+more practical, the application is designed to be simple and easy to understand.
