As an example the nodejs language demonstrate it. In the travis configuration we have to provide the name `node_js` but in the docker registry the official nodejs image is registered as `node`.

 summary: Your very own local CI!
 description: |
   Previs is using the travis configuration file to provide your own local service of continous integration.
   No more accidental error that trigger a fail build, no more plumbing on your git history. 
   But more than a local trevis, it provides you a way of testing in a sandboxed environment.
