+Async Pure JavaScript PostgreSQL driver for node.js
 
 ## ALPHA version
 
-Unlike many githubbers this is my only active project.  All my
-free coding time is to be going towards this until it's production
-ready and stable so watch the repo and stay tuned.
+Implemented in a fully TDD fashion.  Drew major inspiration from
+[postgres-js](http://github.com/creationix/postgres-js) but it has 0 tests and
+doesn't seem to be actively developed anymore.  I'm aiming for
+extremely high quality code, but first doing the implementation and
+only refactoring after tests are in place.  
+
+I'm first aiming to support the low level [messaging
+protocol](http://developer.postgresql.org/pgdocs/postgres/protocol.html).
+
+Due to the fully async nature of node sockets, the driver is
+completely non-blocking.
