Grav is a flat-file based content management system (CMS). Unlike database-backed content management systems like Drupal, Wordpress, or Joomla, Grav generates pages based on folders of Markdown files. This means that site content is stored in a simple format that can be easily modified with standard text editing tools. It also means that no database is required on the web server, just a reasonably standard installation of PHP. Grav's design emphasizes ease of learning, simplicity of setup, and good performance. The Grav developers deliberately avoid adding built-in features that they believe would unnecessarily complicate the software. In the Developers portion of the site, users can locate a link to the Grav documentation. Here, users will find detailed installation instructions, a brief getting started tutorial, and comprehensive reference material. The Requirements section also recommends a number of text editors, Markdown editors, and FTP clients that work well alongside Grav. The Web Servers and Hosting section provides step-by-step instructions for installing Grav on several of the most popular hosting providers.
