Guide

How to get started

Up and running in four steps.

If you have Node.js installed, set it up with a single command:

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

In the terminal, go to your project folder and type claude:

cd my-project
claude

On the first run you'll authorize via your Anthropic account. A browser will open, and you confirm once.

Now just write what you want — generate code, fix a bug, or explain something.

# Ask in plain language
Explain what this project does
Find and fix the bug in the login function
Run all the tests

Tips for the best results

Get more out of Claude.

Be specific. Say exactly what to change — not “make it better”.

Create a CLAUDE.md with /init — Claude reads it every time.

New task? Clear the context with /clear.

Use plan mode for big changes — review before applying.

Drop in a screenshot and say “build this”.

Say “remember this” to save a fact for later.
