 For a general introduction to XOS and how it is used in CORD, see
 http://guide.xosproject.org. The "Developer Guide" at that URL is
 especially helpful, although it is sync'ed with the previous
-release (currently Burwell), which likely lags what's in master.

 Additional design notes, presentations, and other collateral are

 The quickest way to get started is to look at the collection of
-"stock" configurations in *xos/configurations*. The *cord* 
+canned configurations in *xos/configurations*. The *cord* 
 configuration in that directory corresponds to our current 
 CORD development environment, and the README you'll find there
 will help you get started.

 ## What you get
 
 XOS will be set up with a single Deployment and Site.  It should be in a state where
 you can create slices and associate instances with them.
