# Clear Linux* OS `cgit` container image
<!-- Required -->
## What is this image?
`clearlinux/cgit` is a Docker image with `cgit` running on top of the
[official clearlinux base image](https://hub.docker.com/_/clearlinux).
<!-- application introduction -->
> [Cgit](https://git.zx2c4.com/cgit/) is a hyperfast web frontend for git repositories written in C.
For other Clear Linux* OS
based container images, see: https://hub.docker.com/u/clearlinux
## Why use a clearlinux based image?
<!-- CL introduction -->
> [Clear Linux* OS](https://clearlinux.org/) is an open source, rolling release
> Linux distribution optimized for performance and security, from the Cloud to
> the Edge, designed for customization, and manageability.
Clear Linux* OS based container images use:
* Optimized libraries that are compiled with latest compiler versions and
flags.
* Software packages that follow upstream source closely and update frequently.
* An aggressive security model and best practices for CVE patching.
* A multi-staged build approach to keep a reduced container image size.
* The same container syntax as the official images to make getting started
easy.
