Front matter

The keys Vitrine reads at the top of a page, and the start page’s own.

Every page

Key	What it does
`title`	the page’s heading, its name in the browser tab and, unless `linkTitle` is set, in the sidebar, breadcrumbs and pager
`linkTitle`	a shorter name for the sidebar, breadcrumbs, pager and tabs
`weight`	the order among its siblings: lower first; pages without one come last
`lead`	the line under the title, in Markdown; also the page’s description and its summary in lists and llms.txt
`description`	the description for search engines and link previews, if it should differ from `lead`
`math`	`true` loads MathJax for this page, `false` keeps it off when `params.math` is on
`draft`	`true` keeps the page out of the built site; `hugo server -D` shows it

Hugo’s own keys work as usual: date, slug, url, aliases (old addresses that redirect to the page) and build (for example build: { list: never } to keep a page out of the sidebar).

yaml

---
title: Configuration reference
linkTitle: Configuration
weight: 1
lead: Every setting, with its default.

The start page

content/_index.md also reads:

Key	What it does
`facts`	short labels in a row under the lead: `["4 kB gzip", "MIT"]`
`install`	a command in a code block with a copy button: `npm install my-lib`
`actions`	buttons: a list of `{ label, url }`; the first is filled. A `url` from your site is relative to its root (`docs/`), others are full addresses

yaml

---
title: my-lib
lead: What it does, in one or two sentences.
facts: ["4 kB gzip", "0 dependencies", "MIT"]
install: npm install my-lib
actions:
  - { label: Get started, url: docs/installation/ }
  - { label: GitHub, url: "https://github.com/you/my-lib" }
