+Fig makes it nice and easy to run Wordpress in an isolated environment. [Install Fig](install.html), then download Wordpress into the current directory:
+
+    $ curl http://wordpress.org/wordpress-3.8.1.tar.gz | tar -xvzf -
+
+This will create a directory called `wordpress`, which you can rename to the name of your project if you wish. Inside, that directory, we need to write a file that defines what environment your app is going to run in:
 
 ```
 FROM orchardup/php5
-
-ADD http://wordpress.org/wordpress-3.8.1.tar.gz /wordpress.tar.gz
-RUN tar -xzf /wordpress.tar.gz
-ADD wp-config.php /wordpress/wp-config.php
-
-ADD router.php /router.php
+ADD . /code
 ```
 
 This instructs Docker on how to build an image that contains PHP and Wordpress. For more information on how to write Dockerfiles, see the [Dockerfile tutorial](https://www.docker.io/learn/dockerfile/) and the [Dockerfile reference](http://docs.docker.io/en/latest/use/builder/).
