	and url <code>< your jenkins server url >/ghprbhook/</code>.  The url should be composed of your full jenkins server url plus
	the ending <code>/ghprbhook/</code> path.  If your jenkins server is just a domain like https://jenkins.yourcompany.com then the url would look like 
	https://jenkins.yourcompany.com/ghprbhook/.  If your jenkins server is accessed at a path off of a domain like https://yourcompany.com/jenkins 
	then the url would look like https://yourcompany.com/jenkins/ghprbhook/<br/>.  
	Your Jenkins server must be accessible from internet.
