title: Can (and should) I use Lerna without publishing to NPM?
body: <p>I have an app and I have a storybook. They both live inside the same app at the moment. I have just installed Lerna and played around so I can treat them both as 2 separate packages. </p>
  
  <p>Both packages will be dockerised and when I build one, it should not do anything with the other</p>
  
  <p>my structure so far:</p>
  
  <pre><code>app/
    package.json
    lerna.json
    makefile
    packages/
      my-app/
        all-relevant-packages-for-my-app
        package.json
      storybook/
        all-relevant-packages-for-storybook
        package.json
  </code></pre>
  
  <p>I don't want to publish anything to NPM. I simply want to use these packages separately but I would like to import <code>app</code> components into the <code>storybook</code> </p>
  
  <p>is Lerna the correct thing to use here?</p>
  
  <p>when I run say <code>docker build my-app</code> it should go inside the <code>my-app</code> repo and then build the docker image etc, run tests and deploy my app to S3 (this is all set up already) but now I've moved it all I'm wondering if Lerna is the correct tool as I see lots about publishing to NPM</p>
