About

What we do

We regroup everyday commands for Docker, Kubernetes, Git, Linux, Nginx, MySQL, Redis, Python and more into real-work scenarios, so looking up a command becomes a one-second copy instead of digging through docs. All cheatsheets are bilingual (Chinese & English), covering 159+ sheets and 6500+ commands.

Who maintains it

LaoHand is maintained by a team of engineers with 5+ years of hands-on development and production troubleshooting experience, together with open-source contributors. The maintainer and official sources of every sheet are disclosed at the bottom of the page for traceability and correction.

How content is produced

• Traceable sources: every command cites its authoritative reference, and each page lists official links for you to verify and report errors.
• Continuous proofreading: every sheet carries a public update date and is revised as technology versions evolve; the latest proofread time is visible at the bottom of the page.
• Community built: anyone can submit an Issue or Pull Request on GitHub to fix content, making the cheatsheets more accurate over time.

Why trust us

We do not chase "the most entries" — we chase "the most accurate when you need it". Scenario-based grouping, traceable authoritative sources, and publicly listed maintainers with update dates are the three commitments we make for this cheatsheet hub.
