This document provides instructions for setting up a WordPress site on a Raspberry Pi server using a static IP address. It details steps such as installing necessary software like Apache, MySQL, PHP and WordPress using apt-get. It also covers configuring PHP, securing phpMyAdmin with HTTP authentication, creating a MySQL database and user, and generating security keys for WordPress. The document concludes with suggestions for additional configuration tasks and references for more information.
