+Google Chrome Headless - Docker Image

+[Google Chrome Headless](https://developers.google.com/web/updates/2017/04/headless-chrome) is the Google Chrome borwser that can be started without graphical interface to accomplish several tasks (PDF printing, performance, automation...)
+
+Usage
+-----
+
+```
+docker run --rm --name chrome -it -p 9222:9222 --cap-add SYS_ADMIN femtopixel/google-chrome-headless <optional_args> <optional_site_url> 
+```
+
+With `<optional_site_url>` url to your site (e.g. http://www.google.com). By default `about:blank`. You can pass args **BEFORE** the `url` if you want to use some.
+
+By default, Chrome Headless listen on the `9222` port but this can be changed by passing the `CHROME_DEBUG_PORT` environment to the value you want.
+
+### Example
+
+```
+docker run --rm --name chrome -it -p 9000:9000 -e CHROME_DEBUG_PORT=9000 femtopixel/google-chrome-headless <optional_args> <optional_site_url> 
+```
+
+Usage : Improved
+----------------
+
+Using the ever-awesome [Jessie Frazelle](https://twitter.com/jessfraz) SECCOMP profile for Chrome, we don't have to use the hammer that is SYS_ADMIN:
+
+```
+wget https://raw.githubusercontent.com/jfrazelle/dotfiles/master/etc/docker/seccomp/chrome.json -O ~/chrome.json
+docker run --rm --name chrome -it -p 9222:9222 --security-opt seccomp=$HOME/chrome.json  femtopixel/google-chrome-headless <optional_args> <optional_site_url> 
+```
