All done! What now? First, change to the project directory:

	$ cd ${DEST_DIR}

# Run with Docker

The easiest way to run an ICEkit project is with Docker. It works on OS X,
Linux, and Windows, takes care of all the project dependencies like the
database and search engine, and makes deployment easy.

If you haven't already, go install Docker:

  * [OS X](https://download.docker.com/mac/stable/Docker.dmg)
  * [Linux](https://docs.docker.com/engine/installation/linux/)
  * [Windows](https://download.docker.com/win/stable/InstallDocker.msi)

Build a Docker image:

	$ docker-compose build --pull

Run a 'django' container and all of its dependancies:

	$ docker-compose run --rm --service-ports django

Create a superuser account:

	# manage.py createsuperuser

Run the Django dev server:

	# runserver.sh

Open the site in a browser:

	http://localhost:8000

When you're done, exit the container and stop all of its dependencies:

	# exit
	$ docker-compose stop

Read our [Docker guide](http://docs.glamkit.com/en/latest/install/docker.html)
guide for more info on running an ICEkit project with Docker.

# Run without Docker

Read our [Manual Setup](http://docs.glamkit.com/en/latest/install/manual-install.html)
guide for more info on running an ICEkit project without Docker.
