# CLI & agent

Install, register, and run the agent binary, which is agent and command-line interface in one.

- [Install the agent](/docs/guides/cli/install/index.md): Get the amfelt binary onto a host inside your infrastructure and confirm it runs.
- [Register an agent](/docs/guides/cli/register-an-agent/index.md): Create a one-time code in the app, register the agent against it, and keep it connected.
- [Check agent health](/docs/guides/cli/check-agent-health/index.md): Diagnose an agent that will not connect, or prove a fresh install is sound before you run anything.
