title: Import Dockerfile from different local directory via FROM
body: <p>I want to create a multistage build process whereas each of the docker files are nested inside their own directories locally with their corresponding dependencies that are ADDed in for each Docker file. Is there a way to import a Docker file from a different directory locally whereas I am able to import it with Docker's <code>FROM</code> command, to create several stages in a build? </p>
  
  <p>If not, would I be able to <code>ADD</code> the other staged Docker file's into the current Docker file and then use <code>FROM</code> inside the docker container, deleting it after it is added and used in <code>FROM</code>? </p>
  
  <p>Maybe I am thinking about multistage builds the wrong way.</p>
  
  <p>Or can I simply run <code>FROM {path/to/docker/locally}</code>? This is not working for me.   </p>
