 Stock Rotation
 ~~~~~~~~~~~~~~
 
-The stock rotation tool allows library staff to create rotation plans and add 
-items to them. A cronjob is then used to cycle these items round the specified 
-libraries on the rotation plan, moving them to the next stage after the 
-prescribed period of time has passed at the current stage. Email notices may be
-used to provide the library branches with a list of items to be put in-transit 
-to the next branch and if an item is found to be on loan at the time that it 
-should be transfered then an alert will be displayed when it is next returned.
+Stock Rotation helps to spread resources more fairly amongst library branches
+and allows patrons to see a wider range of titles.
+
+Items are popular whilst they are new at a particular branch. However, their
+use often tails off over time. This tool empowers librarians to automate the
+movement of items on to another branch before usage declines and thereby
+extends the items useful life.
