-      # Returns objects for the records responding to either a specific id (1), a list of ids (1, 5, 6) or an array of ids. 
-      # If only one ID is specified, that object is returned directly. If more than one ID is specified, an array is returned.
+      # Find operates with three different retreval approaches:
+      #
+      # * Find by id: This can either be a specific id (1), a list of ids (1, 5, 6), or an array of ids ([5, 6, 10]).
+      #   If no record can be found for all of the listed ids, then RecordNotFound will be raised.
+      # * Find first: This will return the first record matched by the options used. These options can either be specific
+      #   conditions or merely an order. If no record can matched, nil is returned.
+      # # Find all: This will return all the records matched by the options used. If no records are found, an empty array is returned.
+      #
+      # All approaches accepts an option hash as their last parameter. The options are:
+      #
+      # * <tt>:conditions</tt>: 
+      # * <tt>:order</tt>:

       #   Person.find(1, 2, 6) # returns an array for objects with IDs in (1, 2, 6)
