About Reference

Reference is an open source GitHub repository that collects quick reference cheat sheets for developers. The sheets cover many programming languages, markup and configuration formats, and tools, including Python, JavaScript, Go, Rust, HTML, YAML, Docker, and Kubernetes. Each sheet is a brief summary of syntax, commands, or methods rather than full documentation. Contributors can submit new sheets or improvements through pull requests. The original domain, quickref.me, was acquired by a US-based company, and the cheat sheets are now published at cheatsheets.zip, which the project describes as its primary maintained domain.
