Umbraco for Content Editors
The first thing a content editor will see when he logs in to the Umbraco back end for the first time, is a friendly pop-up from the Content Management System (CMS). To get a great head start the 12 step tour throughout the back-end introduces you into the menu and the sections it contains, the tree that is used for content, but also in the media library and other sections. Further it highlights the search functionality and leads you to the help button, which is the end of the welcome tour but the start of two other tours named "Create Content" and "Data Structure". These are good to get an idea on how the system works, but of course The Reference will provide you with a training specific to the custom implementation done on your request.
