Installation

This guide walks you through installing and setting up Claude Code for use with FUSION.

Install Claude Code

Option 1: npm (all platforms)

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

Option 2: Homebrew (macOS)

brew install claude-code

Run the login command to authenticate with your Anthropic account:

claude login

This opens a browser window where you can sign in.

Navigate to the FUSION directory and launch Claude:

cd path/to/FUSION
claude

Claude automatically reads the project’s CLAUDE.md file which contains context about the architecture, coding standards, and key concepts.

Try a simple command to verify everything is working:

> What is FUSION and what are its main components?

If Claude responds with information about the optical network simulator, you’re ready to go.
