Grav uses [markdown]( ../markdown-what is "What is Markdown?") files as content storing, Twig template system for rendering and YAML files for controlling the CMS capabilities.
Grav CMS received the Best Open Source Content Management System (Best Open Source CMS) awards in 2016 and the Best File-Based Content Management System (Best Flat File CMS) awards in 2017 and 2019.
