 HTTPS and Basic Auth are mandatory if you are accessing the dashboard remotely instead of accessing it from `localhost`.
 
+## Run with Docker
+
+It is easy to use it with Docker. First build the image:
+
+```  
+docker build -t parse-dashboard .
+```
+
+Run the image with your ``config.json`` mounted as a volume
+
+```
+docker run -d -p 8080:4040 -v host/path/to/config.json:/src/Parse-Dashboard/parse-dashboard-config.json parse-dashboard 
+```
+
+By default, the container will start the app at port 4040 inside the container. However, you can run custom command as well (see ``Deploying in production`` for custom setup). 
+
+In this example, we want to run the application in production mode at port 80 of the host machine.
+
+```
+docker run -d -p 80:8080 -v host/path/to/config.json:/src/Parse-Dashboard/parse-dashboard-config.json parse-dashboard --port 8080
+```
+
+If you are not familiar with Docker, ``--port 8080`` with be passed in as argument to the entrypoint to form the full command ``npm start -- --port 8080``. The application will start at port 8080 inside the container and port ``8080`` will be mounted to port ``80`` on your host machine.

 ## Deploying in production
 
 If you're deploying to a provider like Heroku, or Google App Engine, the SSL endpoint is terminated early and handled by the provider and you may encounter this error `Parse Dashboard can only be remotely accessed via HTTPS`.
