Léon gives your documentation a calm, readable layout: a tabbed header, a sidebar per tab, a table of contents that follows your reading, and content components written in plain Markdown.
Get started
Install the theme with Composer, then enable it in the configuration of your site.
Composer
composer require cecil/theme-leonArchive
curl -LO https://github.com/Cecilapp/theme-leon/releases/latest/download/leon.zip
unzip leon.zip -d themes/leonThen continue with the Quickstart →
What you can do
Write rich content in Markdown
Callouts, tabs, code groups, steps, accordions and cards use the ::: syntax of Cecil: no HTML, no shortcodes.
Let readers search everything
The search box is powered by FlexSearch: the index is generated at build time, and the search runs in the browser.
Feed your favorite AI assistant
The Copy page button copies the page as Markdown, and the llms.txt file lists all the pages of the site.
