+# luzifer/php5-nginx Dockerfile
+
+This repository contains **Dockerfile** of [Nginx](http://nginx.org/) for [Docker](https://www.docker.com/)'s [automated build](https://registry.hub.docker.com/u/luzifer/php5-nginx/) published to the public [Docker Hub Registry](https://registry.hub.docker.com/).
+
+## Base Docker Image
+
+- [ubuntu](https://registry.hub.docker.com/_/ubuntu/)
+
+## Installation
+
+1. Install [Docker](https://www.docker.com/).
+
+2. Download [automated build](https://registry.hub.docker.com/u/luzifer/php5-nginx/) from public [Docker Hub Registry](https://registry.hub.docker.com/): `docker pull luzifer/php5-nginx`
+
+   (alternatively, you can build an image from Dockerfile: `docker build -t="luzifer/php5-nginx" github.com/luzifer/php5-nginx`)
+
+## Usage
+
+Create a `Dockerfile` similar to the following in your application code folder: 
+
+```
+FROM luzifer/php5-nginx
+
+ONBUILD RUN mkdir -p /application
+ONBUILD ADD . /application
+
+EXPOSE 80
+CMD ["/usr/local/bin/container-run.sh"]
+```
+
+Then, execute the following to build the image:
+
+  docker build -t myuser/myapp .
+
+This will create an image named `myuser/myapp` with your application ready to go.
+To launch it, just type:
+
+  docker run -d -p 80 myuser/myapp
+
+Easy!
