Display markdown from a file resource on an xpage

<?xml version="1.0" encoding="UTF-8"?>
Welcome to this snippet on displaying markdown on an XPage.
You will need to : 
1) download showdown.min.js from https://github.com/showdownjs/showdown/releases
2) save it as a file resource within your nsf ( you can aslo modify the code to use a cdn )
3) create another file resources called demo.md with some markdown in it.
4) download this css file and add it as a CSS resource - https://raw.githubusercontent.com/sindresorhus/github-markdown-css/gh-pages/github-markdown.css
5) paste all of this code here into an empty XPage
6) build and view in a web browser. The text displayed will be the contents of the demo.md file

The contents of the md file is stored in a hidden field using ssjs
The csjs in the script block then converts and renders the text as markdown.
The frig to load the js library first is important.

There is a complete demo database at http://focul.net/showdown
