What is docs?

This repository contains the source files for the official Docker documentation website at docs.docker.com. Docker is a tool that packages software into containers, which are portable, self-contained units that run consistently across different computers. This repository does not contain Docker itself, only the written documentation that explains how to use it. The documentation is entirely open source, meaning anyone can read it, suggest corrections, or submit improvements. The README describes three ways to give feedback: opening a GitHub issue, clicking a feedback button on any page of the documentation site, or using the Request Changes option. Community questions can be directed to the Docker Community Slack workspace, while paid Docker subscribers (Pro, Team, and Business tiers) have access to personalized support. Contributors who want to help improve the docs are pointed to three files in the repository: CONTRIBUTING.md describes the workflow for making changes, STYLE.md covers the writing style and content guidelines, and COMPONENTS.md documents any custom shortcodes or components used in the documentation pages. The repository is written primarily in Markdown, which is a simple text format commonly used for documentation that gets converted into web pages. It is licensed under the Apache 2.0 license and has been maintained since 2013. This is a content repository rather than a code project. If you are looking for Docker Engine, Docker Compose, or other Docker software, those live in separate repositories.
