Claude Code is a terminal-based AI coding assistant for reading, editing, testing, and reviewing code. This section explains how to install it, how permission modes work, and why agentic command-line tools feel different from ordinary chatbots.

Start with Getting Started with Claude Code if you want installation and first-session basics. Read Claude Code: The Deep Dive for the agentic loop, agent teams, MCP, hooks, skills, and practical development workflows. Use the Claude Code command cheat sheet for copyable session instructions, then compare agent choices in Claude Code vs Codex.

Frequently asked questions

Is Claude Code only for professional developers?

No. It is most powerful in real codebases, but the bigger lesson is that AI can now use local tools, inspect files, run tests, and work through feedback loops.

What should I read after installing it?

Read the deep dive, then try a small real task with a clean git status and clear instructions.
