Mastering Plone is intended as a week-long training for people who are new to Plone or want to learn about the current best practices of Plone development.
The training was created by Philip Bauer and Patrick Gerken of starzel.de to create a canonical training for future Plone developers. The aim is that anyone with the appropriate knowledge can give a training based on it and contribute to it. It is published as Open Source on github and training.plone.org.
