The `arkor` CLI is the surface around an Arkor project. After `arkor init`, four commands cover almost everything you do day to day.

| Command | What you do with it |
| --- | --- |
| [`arkor init`](/docs/framework/guides/cli/init) | Drop Arkor into the current directory. Run once per project. |
| [`arkor dev`](/docs/framework/guides/cli/dev) | Launch Studio in the browser. The main interactive loop. |
| [`arkor build` / `arkor start`](/docs/framework/guides/cli/build-and-start) | Run a trainer headlessly: in CI, on a server, or from a script. |
| [`arkor login` / `logout` / `whoami`](/docs/framework/guides/cli/auth) | Sign in to Arkor Cloud or check who you are. |

Run any command with `--help` to see flags. Use a script form when one exists in `package.json` (e.g. `pnpm dev`); otherwise use the package-manager-specific Arkor command shown in the docs for your chosen tab.
