 For testing, you will want to generate an application, and there is a specific issue here: for each application, JHipster installs a local version of itself. This is made to enable several applications to each use a specific JHipster version (application A uses JHipster 3.1.0, and application B uses JHipster 3.2.0).
 
 To overcome this you need to run `npm link generator-jhipster` on the generated project folder as well, so that the local version has a symbolic link to the development version of JHipster.
