 Urbit
 =====
 
-This is an implementation of C. Guy Yarvin's [Nock][1] axioms, a compiler from
-the "Hoon" language to Nock, and other foundations of the [Urbit][2] static
-functional namespace.
+Urbit is a new programming and execution environment designed from scratch. Any
+resemblance to existing languages or operating systems is coincidental,
+cosmetic, or inevitable.
 
-The interpreter depends on the following packages:
+There is a lot to explain. For more information, watch a [demo screencast][1]
+and see the [Urbit website][2].
 
--  GNU Multiprecision library
