 Or mount your own code to be served by PHP-FPM & Nginx
 
     docker run -p 80:8080 -v ~/my-codebase:/var/www/html trafex/alpine-nginx-php7
+
+## Configuration
+In [config/](config/) you'll find the default configuration files for Nginx, PHP and PHP-FPM.
+If you want to extend or customize that you can do so by mounting a configuration file in the correct folder;
+
+Nginx configuration:
+
+    docker run -v "`pwd`/nginx-server.conf:/etc/nginx/conf.d/server.conf" trafex/alpine-nginx-php7
+
+PHP configuration:
+
+    docker run -v "`pwd`/php-setting.ini:/etc/php7/conf.d/settings.ini" trafex/alpine-nginx-php7
+
+PHP-FPM configuration:
+
+    docker run -v "`pwd`/php-fpm-settings.conf:/etc/php7/php-fpm.d/server.conf" trafex/alpine-nginx-php7
+
+_Note; Because `-v` requires an absolute path I've added `pwd` in the example to return the absolute path to the current directory_
