In plain English

Grav is a flat-file content management system (CMS), a way to build websites without needing a database. Instead of storing your content in a database like WordPress does, Grav keeps everything as files on your server. This approach makes it fast and simple to set up: you just extract a ZIP archive and your site is ready to run, with no installation wizard required. Content is written in Markdown, a lightweight formatting system where you use simple symbols like asterisks and hash signs to indicate bold text, headings, and lists. Page layouts and templates are handled by Twig, a templating language from the Symfony family. Configuration files use YAML, a human-readable format that avoids the complexity of XML or JSON. The combination is designed so that non-developers can manage content files directly without touching code. Grav includes a Package Management System called GPM (Grav Package Manager), a command-line tool that lets you install or update plugins and themes with a single command. Plugins are installed via the command line or downloaded from the Grav website. The system is built on top of several established PHP libraries including Symfony components, Doctrine Cache for performance, and a Gregwar image library for on-the-fly image manipulation. PHP version 7.3.6 or higher is required to run it. Grav can be obtained as a ready-built download, installed via Composer (a PHP dependency manager), or cloned directly from GitHub.
