a simple guide for getting a local web server set up
having a web server turned on doesn't necessarily mean you are serving pages on the world wide web. its what allows you to load your own static files (.html, .js etc.) in a browser via http://.
if you're not sure whether or not you have a web server running, no problem! its easy to confirm.
