 #### cabal-dev
 
-cabal-dev works very well if you are working on a single package, but it can be very cumbersome to work on multiple packages at once.
+cabal-dev works very well if you are working on a single package.
+For working on multiple packages at once (installing Yesod), you need to use the shared sandbox feature.
 
 ### Use your development version of Yesod in your application
 
 Note that we have recommended to you to install Yesod into a sandboxed virthualenv environment.
 This is great for development, but when you want to use these development versions in your application that means they are not available through your user/global cabal database for your application.
 You should just continue to use your yesod virthualenv shell for your application.

-You can also use `cabal-dev install` to retrieve these packages.
-cd to your application directory, and the reference the source list.
