## What it does
A community-maintained single-page reference for Claude Code by zebbern, kept up to date with the live Claude Code documentation. Organized into eight sections with jump links: Getting Started, Configuration and Environment Variables, Commands and Usage, Interface and Input, Advanced Features, Automation and Integration, Help and Troubleshooting, and Third-Party Integrations. Every section includes copy-paste examples and settings.json snippets.
Cross-referenced to related community repos maintained by the same author: a Claude Code Discord MCP, 954+ agent skills, a no-cost AI resources list, and 250+ Mermaid diagram templates.
Sections at a glance:
- Getting Started — install commands, system requirements, initial setup steps
- Configuration — complete environment variable list with accepted values and defaults; configuration file locations and precedence; settings.json structure
- Commands — all built-in slash commands with descriptions; CLI flags including rarely documented options
- MCP — how to configure MCP servers in .mcp.json; per-integration examples (JIRA, GitHub, Slack, Postgres)
- Sub-agents — how sub-agents work, how to write agent .md files with frontmatter, the Plan and Explore built-ins
- Hooks — all hook events (PreToolUse, PostToolUse, UserPromptSubmit, Stop, etc.), response format, exit codes
- --dangerously-skip-permissions — exact definition, safe-use conditions (fully sandboxed CI only), what it skips
- Third-Party Integrations — IDE plugins, status-bar integrations, GitHub Actions
## Install
No install needed. Browse the README on GitHub. Use the section links at the top for fast navigation.
## When to use
Use as the first stop for any Claude Code configuration question — environment variables, hook event names and response format, MCP server setup, or the exact behavior of a CLI flag. Faster than searching the official docs for common configuration patterns.
