 Super easy, right? Here's a quick walk through as to what's going on.
 
 * `docker build -t dino/dompdf-module .` builds a docker image that will be used for each run (i.e. each time `docker run` is executed) and tags it with the name `dino/dompdf-module`.
 * `docker run -v composer-cache:/var/lib/composer -v ${PWD}:/opt/app dino/dompdf-module` runs the default build in a new Docker container derived from the image tagged `dino/dompdf-module`. The root of the project and PHP Composer cache volume are mounted so that artifacts generated during the build process are available to you on your local machine.
 
 **Note:** You only need to run the first command once in order to build the image. The second command is what executes the build (build, tests, code quality checks, etc.).

-### Other Supported PHP Versions
-By default, builds executed using Docker are done so using the [latest stable version of PHP](http://php.net/supported-versions.php). If you're adventurous you can execute builds against other [supported versions](http://php.net/supported-versions.php) of PHP.
