Built to turn command references into active practice.

Why this site exists

Development introduces a steady stream of commands and technical terms that are easy to look up once and forget soon afterward. DevCheatsheets was created to make that learning process feel more like playing a game: enter a short scenario, decide which command fits, learn from mistakes, and revisit weak concepts until they become familiar. The goal is to help learners build practical recall through active decisions instead of memorizing isolated definitions.

Who maintains this site?

Content is maintained under the name DevCheatsheets Editorial Team. We do not claim personal professional experience, certifications, or execution results that were not independently verified.

What the site publishes

The current curriculum covers Git, Linux, and Docker through 144 core command concepts, each presented at three difficulty levels. Public command references expose the underlying command library without requiring game progress, and twelve field guides explain complete workflows, failure modes, verification, and safety boundaries. Playable runs provide the interactive practice. The site is independently operated and is not affiliated with Git, the Linux Foundation, Docker, Google, or the documentation publishers it links to.

How missions are created

1. Individual command rooms are derived from an existing command library and receive command-level reference links where available.
2. Multi-step ordering and boss scenarios are written as explicit workflows; list order is never treated as execution order.
3. AI-assisted drafting may be used for scenarios, distractors, and wording, and is disclosed here rather than presented as independent human research.
4. Safety-sensitive commands receive an additional warning and are not presented as safe for every production environment.
5. Corrections are applied to both the mission and its Codex entry.

Source-linked, reviewed, and tested

Source-linked means a relevant reference is provided; it does not by itself claim a full manual audit. Reviewed will be used only after a mission-specific comparison is recorded. Tested will be used only when a reproducible execution check is completed in a named environment. The current build uses source-linked and authored content labels, not a blanket Tested claim.

How the work is documented

The How It Works page explains the scenario, feedback, and weak-concept loop used by the game. Material checks and corrections are published as lab notes; the first note records a live audit of 106 documentation URLs and 18 corrected Linux mappings.

Local-first privacy

No account is required. XP, mastery, unlocked Codex entries, streaks, and active runs are stored in your browser. The first release has no cloud profile or public leaderboard.

Funding and advertising

DevCheatsheets is preparing to use Google AdSense to support free access. Advertising does not determine mission answers, source selection, or editorial corrections. The current build contains no advertising script or ad placement.
