You can run the app by cloning the repository, running 'make,' and opening the index.html in your local webserver (this part is important). You'll also need to view the files in a Webkit browser. That's pretty much it.
If you find a bug (well, um, when you find a bug), please create an issue in the Github issue tracker.
If you're a fan of the Tyee and a whiz with JavaScript, please drop us a line. Better yet, just fork the repository, make changes, and send us a pull request with an explanation of the change.
If you'd like to build an entirely different app, that's even better. In developing Project Coho, we've taken steps toward releasing a public API to The Tyee's data. Keep an eye on api.thetyee.ca over the coming weeks for more info.
Enjoy.
