what is reference fr?

Quick Reference is a collection of developer cheat sheets, aimed primarily at a Chinese-speaking audience. The README describes it as a curated set of short reference pages for common technologies, tools, and development workflows, designed to help readers look up key information quickly and work more efficiently. It is a translation and expansion of an existing English Reference project, with additional content added by the maintainer. The repository itself is a content project rather than a software library. Although the listed primary language is Dockerfile and there is a published Docker image on Docker Hub, the bulk of the value is in the written cheat sheets. The topics on GitHub mention areas such as JavaScript, npm, React, and Docker, which gives a rough sense of what subjects are covered. The README does not list the individual cheat sheets in the visible portion shown here, so the exact catalogue is not described in this clip. Contributions are explicitly invited. The author asks readers to share their own cheat sheets and offers to incorporate them, and welcomes pull requests to fix or improve existing content through a CONTRIBUTING guide linked from the README. The project is described as continuously updated. A large part of the README is a sponsorship section. The maintainer thanks supporters of their open source work and points to a sponsorship page, and also lists a long set of independently developed macOS applications, such as Scap, Screen Test, Deskmark, Keyzer, Mousio, Musicer, DevTutor, RegexMate, and others, which readers can download to support the project. CI badges, Docker Hub badges, and follow links for X and Buy Me a Coffee are included at the top of the README. The full README is longer than what was shown.
