PORTAL / GETTING STARTED / Phase 2 — Install Claude Code

Phase 2 — Install Claude Code

Get the terminal that runs everything onto each team member's machine. 10 minutes per person.

Claude Code is the interface to your operating system: your team types plain language ("build the campaign from this brief"), the system does the work. One install per team member.

Windows

  1. Install Node.js LTS from nodejs.org (accept all defaults).
  2. Install Git from git-scm.com (accept all defaults — this includes Git Bash).
  3. Open Terminal (or PowerShell) and run:
npm install -g @anthropic-ai/claude-code
  1. Then run claude — a browser window opens, log in with the Claude Max account from Phase 1.

Mac

  1. Open Terminal (Cmd+Space → "Terminal").
  2. Install Homebrew if you don't have it: instructions at brew.sh.
  3. Run:
brew install node git
npm install -g @anthropic-ai/claude-code
  1. Run claude and log in when the browser opens.

Verify it works

claude --version

If a version number prints, you're done. If the command isn't found, close and reopen the terminal first — that fixes it 9 times out of 10.

Clone your repo

In the terminal, pick where the system lives on this machine (e.g. your home folder) and run:

git clone https://github.com/YOUR-ORG/agency-os.git
cd agency-os
claude

From now on, this is the daily routine: open terminal → cd agency-os → claude → say what you need.
