-Promotions
-==========
+= Promotions
+
+Basic support for selecting a group of products to highlight
+
+- usage
+
+set promotions by calling "Promotions.create :product => some_prod" in the
+console etc (no nice admin interface yet)
+
+call Promotions.random_subset(n) to get n products
+
+
+- implementation etc
+
+at present: just a table of ids, with no uniqueness checking
+
+please see the TODO list
-Provides basic support for highlighting products, eg for a front page
-Currently experimental, as I migrate to 0.6.x
