+
+Hi there! This is the course repo for Udacity Web Accessibility. Contained in
+this repo are a number of sample exercises to help you improve your
+accessibility skills.
+
+## Running the examples
+
+Most of the examples can just have their `index.html` dragged into the browser
+in order to run. Some examples may require running a local server, an easy
+way to run a local server is with [the Web Server for Chrome extension](https://chrome.google.com/webstore/detail/web-server-for-chrome/ofhbbkphhbklhfoeikjpcbhemlocgigb?hl=en). If you need to run a local server for an example we'll
+be sure to note this requirement in the example's README as well as in the
+course instructor notes.
+
+## Found a bug?
+
+Please feel free to [create an issue](https://github.com/udacity/ud891/issues/new)
+if you find anything wrong with the exercises.
