27 pages of plain-English software engineering foundations + a 30-term AI cheat sheet — for free.

Every Reddit thread, tutorial, and Anthropic doc page assumes you already speak fluent dev. This is the guide that closes the gap.

What you get

• The Terminal — beyond cd and ls — the 12 commands that unlock 90% of terminal work, paths, pipes, redirects, env vars

• IDEs — your code editor done right — why VS Code, the 6 day-one extensions, the 8 keyboard shortcuts that change everything

• Git & GitHub — the "save game" mental model — the 7 commands you actually use, branches, the PR workflow in plain English

• APIs — how programs talk to each other — HTTP, REST, JSON, status codes, the three auth patterns

• Security primer — the four-things rule — never commit secrets, validate inputs, HTTPS everywhere, hash passwords

• The 30-term AI Jargon cheat sheet — Agent · API · MCP · Token · Context window · RAG · 25 more

Why this is free

This is foundation knowledge. Charging for foundations gates people out who'd most benefit from the paid guides. Free is the right answer.
