If you’ve been around web servers for very long, you’ve probably heard someone refer to the “LAMP stack.” And whether or not that’s true, you probably have some interest in how WordPress actually presents pages to the Internet.

In doing so I hope you get a basis through which to understand all the ways you may use WordPress for development, making local changes, and maybe even hosting it yourself.
