+# What's this all about?
+
+`simple-actors` is a haskell eDSL for writing highly-structured concurrent
+programs based on the so-called 
+[Actor Model](http://en.wikipedia.org/wiki/Actor_model). It provides a far
+more structured way of organizing concurrent code than ad-hoc use of `Chan`,
+`forkIO` and `MVar`s.
+
+The library was designed to make easy to implement message-passing algorithms
+and the like, but as I work on it and learn more about distributed computing,
+I'm hoping it can be used across the network eventually.
+
+# How do I do it?
+
+Install with a 
+
+    cabal install simple-actors
+
+and check out the docs [here](http://hackage.haskell.org/package/simple-actors).
