We've developed a series of articles to help you come on board. Click through the menu on the right hand side to read each one. Please leave comments if there's some useful information you would like to see.
Putting information into a "book" like this is a great way to structure a linked series of pages. It can work with any number of chapters and subsections. We are using this feature for the Embark wiki as well.
Not everyone has access to the Books feature so if it is likely to suit some of your content, please get in touch for additional permissions.
