+The query UI helps with testing the system for queries.
+
+Things to note:
+   + It is written with the assumption that it is being run dynamically.
+     As such, it's recommended to be used with a server or a dynamic environment
+     (like http://brackets.io), because it otherwise just shows the autocomplete bar.
+   + To send Interests and get Data, it'll need to integrate the NDN-JS codebase.
