🎯 In one sentence: Claude Code is a command-line tool that lives in your terminal, understands your entire codebase, and lets you code through natural language — editing files, running commands, and managing git.

What is Claude Code?

Imagine having a senior developer sitting next to you in your terminal. You tell them what you want in plain English, and they read your code, make changes, run tests, commit to git, and explain what they did. That's Claude Code.

It's not a chatbot in a browser — it's an agent that operates directly on your files. It can:

• Read and understand your entire project structure
• Edit multiple files at once
• Run terminal commands (build, test, lint, etc.)
• Create new files and directories
• Manage git (commits, branches, PRs)
• Debug errors by reading logs and stack traces
• Explain code and architecture decisions

Who is it for?

Claude Code is for anyone who writes code, regardless of experience level:

• Beginners: Get help understanding codebases, fixing bugs, and learning patterns
• Intermediate devs: Speed up development, automate repetitive tasks, get code reviews
• Senior devs: Rapid prototyping, large-scale refactoring, architecture exploration

You need a Pro, Max, Team, or Enterprise plan to use it (or API credits).
