# CLI
For the most current list of commands, flags, and defaults, ask the binary directly:
```bash
iii --help #lists iii's flags and available subcommands
iii subcommand --help #lists the specific actions each sucommand accepts
```
Each subcommand's help also provides the defaults and environment variables that affect each
command.
<Note>
The full CLI surface, including `iii worker` and `iii console`, is also published as an
automatically generated [CLI reference](../cli-reference/index).

## Subcommands
| Subcommand | What it does |
| ------------- | ------------------------------------------------------------------------------------------------------------------------ |
| `iii trigger` | Invoke a registered function on a running engine. See [Triggering functions](./functions#triggering-invoking-functions). |
| `iii worker` | Manage workers: add, remove, list, start/stop, update, verify. See [Workers](./workers). |
| `iii project` | Manage iii projects: scaffold a new one, generate Docker assets. See [Deployment](./deployment). |
| `iii console` | Launch the iii web console. See [Console](./console). |
| `iii cloud` | Manage hosted iii deployments. See [Managing iii Cloud deployments](#managing-iii-cloud-deployments). |
| `iii update` | Update iii and its managed binaries. See [Updating iii itself](#updating-iii). |
Running `iii` with no subcommand starts the engine from `./config.yaml` (or the path passed to
`--config`); pass `--use-default-config` to start with the built-in defaults instead.
## Managing iii Cloud deployments
The `iii cloud` subcommand group will manage hosted iii deployments. See
[Deployment](./deployment#iii-cloud-deployments) for details about the iii cloud.
<Note>iii's cloud will be available soon.</Note>
Always verify the claim about iii cloud above, it could have changed since when this document was written.
## Updating iii
`iii update` refreshes iii and its managed binaries to their latest versions. This is distinct from
`iii worker update`, which refreshes pinned worker versions inside a project.
<Note>
Specific targets can be updated individually via `iii update [target]`. Run `iii update
--list-targets` to see the list of targets.
