This will fire up the website inside a Docker container and start listening on port 4000.
Simply connect your browser to http://localhost:4000 and you're good to go. In development
mode, the site has the [jekyll:livereload](https://github.com/RobertDeRose/jekyll-livereload) extension enabled, allowing you to see your changes immediately
upon saving files in the source directory.
## Deploying the site
TODO: Set up webhook for auto-deployment on push to master.
