What's Wrong or Missing?

After a successful pip install claude-code, the current README.md does not provide immediate guidance on the essential next steps a user should take.

Users are left without knowing how to:

• Authenticate (claude login)
• See available commands (claude --help)
• Start their first session

This creates a significant point of friction during the onboarding of new users, who may feel lost after the installation.

Suggested Improvement

Add a "Getting Started" section to the README.md immediately after the Installation section. This section should provide a concise, step-by-step guide for a user's first run:

Impact

Medium - Makes feature difficult to understand

Additional Context

I'm happy to create a Pull Request with these changes. I can ensure the new section is well-formatted and, if the maintainers find it helpful, I can expand it with more detailed examples to make the onboarding process as smooth as possible for new users.
