wtf is docs?

This repository holds all the written guides and instructions for TiDB, which is a distributed database system. Think of it as the instruction manual for how to install, use, and troubleshoot TiDB, it's the central place where all official documentation lives before it gets published to the web. The repository is organized by language (English and Chinese are officially maintained, with other languages available through translation tools) and by version. Since TiDB releases new versions regularly, this repo keeps separate documentation branches for each major release, so if you're using version 5.4, you can read docs written specifically for that version, while developers working with the latest development build can access cutting-edge docs on the master branch. When TiDB's creators push out updates, the documentation gets updated alongside the code. Anyone can contribute to these docs. If you're using TiDB and spot something confusing, outdated, or wrong in the documentation, you can open an issue to report it or submit a pull request (a direct edit) to fix it yourself. This is a community-driven effort, the repository welcomes help from users, developers, and anyone who wants to improve how TiDB is explained. The README even includes a contribution map showing who's helped out so far, treating documentation work as a recognized form of contribution to the project. The README doesn't go into detail about the technical infrastructure behind how these docs are built or deployed, but it's clear the project takes documentation seriously across multiple languages and maintains historical versions so users on older releases can still find relevant guidance.
