[Wagtail] is a new Open Source [Django]-based CMS. In this 20 minute tutorial we will see how you can create a blog from scratch using Wagtail. If you want to see some more examples of usage please take a look at the [wagtaildemo] GitHub project.
To follow this tutorial you will need to have [Python] 2.7 installed with a working version of [pip] and [virtualenv].
