Subject: [PATCH] Add documentation on logging

I spent a long time trying to figure out why my `/var/log/nginx/error.log` and `/var/log/nginx/access.log` were always empty before finding this great blog article : https://blog.docker.com/2015/04/tips-for-deploying-nginx-official-image-with-docker/.
Putting this directly in the docs should save time to a lot of users working with this image.

+#### Logging
+
+Access and error logs are sent to the Docker log collector by default by linking them to stdout and stderr, which causes all messages from both logs to be stored in the file/var/lib/docker/containers/\<container id\>/\<container id\>-json.log on the Docker Host. To access the logs from the command line :
+
+    docker logs <container name>
