 # vagrant-boxen
 
-It's kinda stupid that each build I have to download the same packages over and 
-over. *vagrant-boxen* is a collection of Vagrant boxes with them already installed,
-so things run faster.
+**Problem:** installing same things over and over makes builds long
+
+**Solution:** make Vagrant images with common things preinstalled
 
 Boxes are based off *debian/contrib-jessie64*
 
+## List o'boxes

 * [Cassandra + ZooKeeper + RabbitMQ](/cass_zk_rmq)
