# Atmos CLI

Atmos is a CLI for provisioning infrastructure with Terraform, Helmfile, Packer, and more, and for running workflows and custom commands.
Run `atmos` without arguments to display usage and available commands, including configured custom commands. No stack configuration is required to display help.

## Usage

Run any of these commands to display help:

```shell
atmos
atmos --help
atmos help
```

To see usage and options for a specific command, append `--help`:

```shell
atmos workflow --help
atmos terraform plan --help
```

:::tip
To quickly check the Atmos version, use `atmos --version` or `atmos version`. See the [version command](/cli/commands/version/usage) for more details.
