 # nginx-php56
-Docker - Nginx and PHP 5.6
+A Nginx + PHP 5.6 (FPM) Base container. This container is based on the excellent [phusion/baseimage-docker](https://github.com/phusion/baseimage-docker) base container.
+
+### Services
+All services are defined and managed using the phusion/baseimage methodology. Logs are output using syslog and can be accessed using ``docker logs {container}``.
+
+* Nginx
+* PHP-FPM (5.6)
+
+### Default Settings
+The container sets up a www root folder in the following location:
+
+``/var/www/public``
+
+As a final task a demo index.php is copied to this location.
+
+### Volumes
+The following folder is specified as a volume:
+
+``/var/www/``
+
+Note that the ``/var/www/public`` is actually the root folder for serving PHP files for your web server. Having a layer back for the volume allows a bit more control over what files are visible.
+
+### Build Folder (within repo)
+The build folder contains the nginx config files as well as php-fpm settings and a setup.sh file that offloads tasks from the Dockerfile.
+
+### Notes
+Remember that PHP-FPM doesn not respect environment variables passed in the traditional manner. You will need to explicitly state what your variables are within the ``/etc/php5/fpm/pool.d/www.conf`` file.
