# Capa documentation

Source: https://capacms.com/docs

Guides and reference for building with Capa, editing in it, and running it for clients.

Capa is a hybrid headless CMS. Your team writes and publishes in the admin, and your sites, apps and agents read the content through a cached API.

## For agents

These docs are also plain Markdown. [`/llms.txt`](https://capacms.com/llms.txt) lists every page, [`/llms-full.txt`](https://capacms.com/llms-full.txt) holds all of them in one file, and any page is available as Markdown by adding `.md` to its URL, like [`/docs/api/entries.md`](https://capacms.com/docs/api/entries.md).
