About Learn X in Y minutes

Learn X in Y Minutes is a reference site offering quick-tour guides to programming languages, frameworks, libraries, and developer tools, presented as runnable code examples with inline comments explaining syntax and features. Coverage spans a large number of programming languages (including mainstream languages like Python, JavaScript, Java, C++, and Rust as well as many more niche and esoteric ones), plus entries for frameworks and libraries (jQuery, OpenCV, PyQt, Qt, raylib, p5.js), developer tools (Git, Docker, Vim, tmux, Make, Ansible), and topics in algorithms and data structures (Dynamic Programming, Lambda Calculus, Set theory).

Many guides are available in translated versions across dozens of languages. The project is community-driven, with content contributed and licensed under CC BY-SA 3.0, and new language guides are added via pull requests on GitHub. It is aimed at developers who want a fast, condensed introduction to a new language or tool's syntax and core concepts rather than a full tutorial or documentation set.
