"The Guide is an application that allows you create documents ("guides") which inherently have a tree (which you can modify as you please) and text associated with each node of the tree. The text itself is of the rich-text variety, and the editor allows you to modify the style and formatting of the text (fonts, bold, italics etc).For the initiated, the Guide is a two-pane extrinsic outliner. This concept is similar to mindmapping in some ways."
