# Configuration

You can save frequently used configuration settings in a file. By default, the file is located at `~/.vgs/config` on Linux or macOS, or at `C:\Users\USERNAME\.vgs\config` on Windows.

You may override this location by either setting an environment variable, `VGS_CONFIG_FILE`, or with a CLI option when invoking a command:

```bash
vgs login --config ./config
```

## Format

The CLI expects config files to be compatible with [ConfigObj](https://configobj.readthedocs.io/en/latest/configobj.html)

```bash
[login]
idp = ACgymeNXPo5CkQ5cZcmJvPQj
```

You may be familiar with this format if you've ever used the AWS CLI.

## Supported Settings

### Section: `login`

| Setting | Description                |
| ------- | -------------------------- |
| `idp`   | Custom IdP to log in with. |

## Configuration Settings and Precedence

Configuration sources for the VGS CLI take precedence in the following order:

1. **Command line options** – Explicitly specified options like `--idp` or `--vault`.
2. **Environment variables** – You can store values in your system's environment variables.
3. **Configuration file** – The CLI can read settings from a file.
