# Install oo CLI

Please help me install and verify oo-cli:
1. Read the install guide https://cli.oomol.com/install-guide.md
2. Follow the guide and first check whether `oo` is already available on this machine. If it is missing, use the install command from the guide that fits the current platform.
3. Run `oo --version` to verify the installation result.
4. Run `oo login`.
