Claude Code Setup Guide

Claude Code is a terminal-based AI coding agent from Anthropic. It reads your codebase, edits files, runs tests, and commits -- all autonomously.

Install

npm install -g @anthropic-ai/claude-code

CLAUDE.md -- Your project's AI brain

Create a CLAUDE.md in your project root. This file tells Claude Code about your project:

# My Project

## Stack
Next.js 16 + Convex + Clerk + Tailwind CSS v4

## Key Directories
- src/app/ -- Pages and layouts
- src/components/ -- React components
- convex/ -- Backend functions

## Commands
- npm run dev -- Start dev server
- npx convex dev -- Start backend

MCP Servers

Connect external tools to Claude Code via MCP:

{
  "mcpServers": {
    "devdigest": {
      "command": "dd",
      "args": ["mcp"]
    }
  }
}

Sub-agents

Claude Code can spawn sub-agents for parallel work:

Use the Task tool to spawn agents for:
- Research tasks
- Independent file edits
- Running tests in parallel

Tips

• Keep CLAUDE.md under 200 lines -- concise beats comprehensive
• Use memory files in .claude/ for session-specific context
• Run claude --dangerously-skip-permissions for fully autonomous mode (use with caution - see the permissions guide for safer allow and deny rules)

FAQ

How do I install Claude Code?

Run npm install -g @anthropic-ai/claude-code. You need Node.js 18+, a terminal on macOS, Linux or WSL, and an Anthropic subscription (Pro or Max).

What should go in a CLAUDE.md file?

Put a CLAUDE.md in your project root that describes your stack, your key directories and the commands you run, such as starting the dev server and the backend. Keep it under 200 lines - concise beats comprehensive.

How do I connect MCP servers to Claude Code?

Add an entry under mcpServers in your MCP config with the command to launch and its args. The example in this guide registers a server named devdigest that runs dd mcp.

Can Claude Code run tasks in parallel?

Yes. Claude Code can use the Task tool to spawn sub-agents for research, independent file edits and running tests in parallel.
