We recommend using [virthualenv](http://hackage.haskell.org/package/virthualenv) when hacking on Yesod.
This is optional, but prevents your custom build of Yesod from interfering with your currently installed cabal packages.
virthualenv creates an isolated environment like cabal-dev.
cabal-dev isolates a single cabal package, but virthualenv isolates multiple packages together.
cabal-dev by default isolates a single cabal package, but virthualenv isolates multiple packages together.
cabal-dev can isolate multiple packages together by using the -s sandbox argument

### Use your development version of Yesod in your application
Note that we have told you to install Yesod into a sandboxed virthualenv environment.
This means it is not available through your user/global cabal database for your application.
Instead you should use `cabal-dev install` to retrieve these packages.

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.
