 Non-blocking MySQLi database access with PHP.
 Designed to work with [reactphp/react](https://github.com/reactphp/react).

+    $db->loop->run();

+Setting `shuttingDown` to true will allow the loop to exit once the query has resolved.

 This won't work out of the box without the database configured.
-As of this point, database configuration is hard coded.
-Still need to pull out the configs. You will also need to
-set up a database with some data to query. Check back later
-for more!
+You will also need to set up a database with some data to query.
 
-## TODO
+## Unit Tests
 
-A lot.
+The example and unit tests expect a database called `react_mysql_test` which it
+will populate with the proper tables each time it runs. It also expects `localhost`
+and a user `apache` with password `apache`.

+## TODO
 
 This is not production ready. Still tons to do on the query builder.
 While I hate to reinvent the wheel, I have not found a lightweight
