Tip: Start Your Own Local Web Server
In ruby
$ ruby -run -e httpd . -p 8080
Tip - change github.com download / fetch links / urls to githubusercontent.com.
github.com gets blocked in browser security (CORS header set to render.github.com domain only or such)
the githubusercontent.com (CORS header) is set to * (thus, available to all domains)
