 ## Features
 
-* Values are serialized, so arrays and objects can be stored and restored.
+* Virtually unlimited collections with virtually unlimited keys.
+* Every key can have any number of values with a validity range, and a fallback key without
+  a validity range for when no range matches.
+* Values are serialized, so arrays and objects are okay to use.
 * Not intended to be running as a public service, so there is no authentication, for now.
-* Last value that matches is returned.
 
 ### Future
 
 * Metadata; store with key "meta" in value set post call, returned under a "meta" key in the
   result list.
