Install the CLI

What changes

Install sumr on a local machine before starting Playbook, Mission, or Kontract workflows.

When this helps

• A machine does not have the sumr command yet.
• A teammate is setting up a project for the first time.
• You need a short install link instead of sending the full CLI reference.

Run this command

$brew install sumr# install the CLI$sumr --version# confirm it runs

Flags you can use

Homebrew handles this install step, so there are no SUMR CLI flags.

Keep in mind

• Run commands from the repository that owns the work unless the command page says otherwise.
• Prefer repo scripts when a project wraps SUMR CLI behavior with its own Bun commands.
