# liken

> `liken` is a small operating system that boots a machine directly
> into Kubernetes. This site is its manual.

Every page of this site is also served as Markdown: append index.md
to the page's URL. /llms-full.txt holds the whole manual in one file.
The repository at https://github.com/liken-sh/liken is the deep
documentation.
