+You can use Docker Compose to easily run WordPress in an isolated environment built

+[Compose installed](install.md).
 
 ## Define the project
 
-First, [Install Compose](install.md) and then download WordPress into the
-current directory:
+1. Create an empty project directory.
 
-    $ curl https://wordpress.org/latest.tar.gz | tar -xvzf -
+    You can name the directory something easy for you to remember. This directory is the context for your application image. The directory should only contain resources to build that image.
 
-This will create a directory called `wordpress`. If you wish, you can rename it
-to the name of your project.
+    This project directory will contain a `Dockerfile`, a `docker-compose.yaml` file, along with a downloaded `wordpress` directory and a custom `wp-config.php`, all of which you will create in the following steps.
 
-Next, inside that directory, create a `Dockerfile`, a file that defines what
-environment your app is going to run in. For more information on how to write
-Dockerfiles, see the
-[Docker user guide](https://docs.docker.com/engine/userguide/dockerimages/#building-an-image-from-a-dockerfile) and the
-[Dockerfile reference](https://docs.docker.com/engine/reference/builder/). In
-this case, your Dockerfile should be:
+2. Change directories into your project directory.
 
-    FROM orchardup/php5
-    ADD . /code
+    For example, if you named your directory `my_wordpress`:
 
-This tells Docker how to build an image defining a container that contains PHP
-and WordPress.
+        $ cd my-wordpress/
 
-Next you'll create a `docker-compose.yml` file that will start your web service
-and a separate MySQL instance:
+3. Create a `Dockerfile`, a file that defines the environment in which your application will run.

+    In this case, your Dockerfile should include these two lines:

-    define('DB_NAME', 'wordpress');
-    define('DB_USER', 'root');
-    define('DB_PASSWORD', '');
-    define('DB_HOST', "db:3306");
-    define('DB_CHARSET', 'utf8');
-    define('DB_COLLATE', '');
+        FROM orchardup/php5
+        ADD . /code
 
-    define('AUTH_KEY',         'put your unique phrase here');
-    define('SECURE_AUTH_KEY',  'put your unique phrase here');
-    define('LOGGED_IN_KEY',    'put your unique phrase here');
-    define('NONCE_KEY',        'put your unique phrase here');
-    define('AUTH_SALT',        'put your unique phrase here');
-    define('SECURE_AUTH_SALT', 'put your unique phrase here');
-    define('LOGGED_IN_SALT',   'put your unique phrase here');
-    define('NONCE_SALT',       'put your unique phrase here');
+    This tells the Docker Engine daemon how to build an image defining a container that contains PHP and WordPress.
 
-    $table_prefix  = 'wp_';
-    define('WPLANG', '');
-    define('WP_DEBUG', false);
+4. Create a `docker-compose.yml` file that will start your web service and a separate MySQL instance:
 
-    if ( !defined('ABSPATH') )
-        define('ABSPATH', dirname(__FILE__) . '/');
+        version: '2'

+            environment:
+              MYSQL_DATABASE: wordpress
 
-    require_once(ABSPATH . 'wp-settings.php');
+5. Download WordPress into the current directory:
+
+        $ curl https://wordpress.org/latest.tar.gz | tar -xvzf -
+
+    This creates a directory called `wordpress` in your project directory.
+
+6. Create a `wp-config.php` file within the `wordpress` directory.
+
+    A supporting file is needed to get this working. At the top level of the wordpress directory, add a new file called `wp-config.php` as shown. This is the standard WordPress config file with a single change to point the database configuration at the `db` container:
+
+        <?php
+        define('DB_NAME', 'wordpress');
+        define('DB_USER', 'root');

+
+        define('AUTH_KEY',         'put your unique phrase here');
+        define('SECURE_AUTH_KEY',  'put your unique phrase here');
+        define('LOGGED_IN_KEY',    'put your unique phrase here');
+        define('NONCE_KEY',        'put your unique phrase here');
+        define('AUTH_SALT',        'put your unique phrase here');
+        define('SECURE_AUTH_SALT', 'put your unique phrase here');
+        define('LOGGED_IN_SALT',   'put your unique phrase here');
+        define('NONCE_SALT',       'put your unique phrase here');
+
+        $table_prefix  = 'wp_';
+        define('WPLANG', '');
+        define('WP_DEBUG', false);

+          define('ABSPATH', dirname(__FILE__) . '/');
+
+        require_once(ABSPATH . 'wp-settings.php');
+        ?>
+
+7. Verify the contents and structure of your project directory.

 ### Build the project
 
-With those four files in place, run `docker-compose up` inside your WordPress
-directory and it'll pull and build the needed images, and then start the web and
-database containers. If you're using [Docker Machine](https://docs.docker.com/machine/), then `docker-machine ip MACHINE_VM` gives you the machine address and you can open `http://MACHINE_VM_IP:8000` in a browser.
