SimpleEditions is a crowdsourced tutorial web site being developed in Python for Google App Engine. The site is available at http://www.simpleeditions.com/.
First of all, you will need to have the Google App Engine SDK installed.
After cloning this repository, you will need to copy src/simpleeditions/settings.py.template to src/simpleeditions/settings.py. Once this has been done, launch the Google App Engine development server and browse to the local address (http://localhost/ by default).
