Setting up and running

Setting up and running a multi-site installation is more complex than a single-site install. Reading this page should help you to decide if you really need a multi-site install, and what might be involved with creating one. If the instructions on this page make no sense to you, be sure to test things on a development site first, rather than your live site.
you want to run a network of blogs you should at least have a basic understanding of UNIX/Linux administration. A basic knowledge of WordPress development, PHP, HTML and CSS is recommended as well.
