When to use it

- You want to understand thinking modes, plan/auto mode, subagents, skills, or MCP setup before using them.
- You are onboarding a teammate and want a vetted, single-link primer instead of scattered docs.

How to use it
This is a reference guide, not a skill or plugin — there is nothing to install. Read it on GitHub or clone it for offline use.
git clone https://github.com/zebbern/claude-code-guide
The README is the deliverable: a single page covering installation paths (native installer, npm @anthropic-ai/claude-code, Docker), environment variables, the memory hierarchy, slash commands, CLI flags, thinking/effort modes, plan/auto mode, subagents, skills, worktrees, and MCP/plugin setup. The agents/ and skills/ directories hold example definitions you can copy as starting templates; CHANGELOG.md tracks revisions.
Note: the curl/npm install commands inside the README install Claude Code itself (the subject of the guide), not this repository.
Why it earns its place
One of the most-starred (~4.3k) community references for Claude Code, kept current (460+ commits, MIT) by zebbern. It consolidates the full command and configuration surface — env vars, slash commands, flags, shortcuts, agents, skills, MCP — into a single scannable page, which is faster than hunting across official docs for a flag or keyword. Useful as both a learning path (beginner to power user) and a day-to-day cheatsheet.
