tldr (tldr-pages) is a community-driven collection of cheat sheets that summarize the usage of command-line tools in a few lines of practical examples. Instead of long, detailed man pages, passing a command name as in tldr tar shows only common usage examples and short descriptions, and the pages are maintained in Markdown format on GitHub. There are clients implemented in several languages, including Node.js, Python, and Rust (tealdeer), and pages are available translated into multiple languages.
