# Templates (/docs/maintain/_templates)

A starting point for each document type. Copy the file into its directory, fill it in, and
delete what does not apply. Each one is a Markdown page with a frontmatter `title`
([ADR-0002](../adr/ADR-0002-living-design-documentation.mdx)) and `description`, a required line
([ADR-0035](../adr/ADR-0035-every-page-is-ready-for-search-and-sharing.mdx)) whose placeholder the build
can't tell from your own, so replace it.
