Getting Started Guide
Step-by-step instructions for non-technical users.
- 1
Install via npm
Run `npm install -g @anthropic-ai/claude-code` in your terminal. You need Node.js 18+ installed.
- 2
Authenticate
Run `claude` and follow the authentication prompts. You can use API keys or a Claude Max subscription.
- 3
Open your project
Navigate to your project directory and run `claude`. It automatically indexes your codebase for context.
- 4
Start with a small task
Try "fix the failing test in auth.test.ts" or "add input validation to the signup form." Claude Code reads, edits, and runs tests.
- 5
Scale to bigger tasks
Once comfortable, try larger refactors: "migrate this Express app to use TypeScript" or "add pagination to all API endpoints."
Frequently Asked Questions
Claude Code vs Cursor — which should I use?
Claude Code is terminal-based and agentic — it runs commands and edits files autonomously. Cursor is a GUI editor with AI suggestions inline. Use Claude Code for large refactors and Cursor for daily coding.
How much does it cost?
You can use it with API credits (pay-per-token) or a Claude Max subscription ($100-200/mo). Heavy usage on the API can cost $50-200/mo depending on project size.
Can it break my code?
Claude Code edits files directly, so use git for safety. It typically runs tests after changes and can fix issues it introduces. Always review diffs before committing.
