 A simple and modern, type safe, idiomatic Haskell client for
 [Prometheus](http://prometheus.io) monitoring. Specifically there is
 no use of unsafe IO or manual ByteString construction from lists of
-bytes. Batteries-included web server.  .  [Usage Example]
+bytes. Batteries-included web server. Version 0.* supports Prometheus v1.0
+  and version 2.* supports Prometheus v2.0.
