+@item @strong{Home} - The home view is for long term tracking and allows you to work with charts that 
+plot and analyse metrics. It is intended to be used to reviewing progress and identify what is and is
+not working (or perhaps historically, what has worked and what hasn't).
+
+In this view the scope is @emph{generally} limited to the date range or season selected in the associated
+sidebar -- the currently selected ride is not relevant in this view.
+
+@item @strong{Diary} - The diary view is for tracking recent rides - looking at the data in terms of the 
+last day, week or month. As planning functions arrive in v3.1 this view will become more funcitonally
+rich, but for now it is more or less a configurable version of the old @emph{Weekly Chart}.
+
+In this view the scope is limited to the day, week or month of the currently selected activity. As you
+select different activities the date range changes to reflect this.
+
+To select the summarisation level (day, week or month) the summary sidebar contains a drop down selector.

+As well as using the numerous analysis charts you can also edit and adjust the telemetry data within
+the activities and add your own narratives and texts.  The narrative fields are configurable to 
+your tastes, see `Metadata' in chapter 4.
