# Configuration
Sunshine will work with the default settings for most users. In some cases you may want to configure Sunshine further.

The default location for the configuration file is listed below. You can use another location if you
choose, by passing in the full configuration file path as the first argument when you start Sunshine.

**Example**
```bash
sunshine ~/sunshine_config.conf
```

The default location of the `apps.json` is the same as the configuration file. You can use a custom
location by modifying the configuration file.

**Default Config Directory**

| OS      | Location                                        |
|---------|-------------------------------------------------|
| Docker  | @code{}/config@endcode                          |
| Linux   | @code{}~/.config/sunshine@endcode               |
| macOS   | @code{}~/.config/sunshine@endcode               |
| Windows | @code{}%ProgramFiles%\\Sunshine\\config@endcode |

Although it is recommended to use the configuration UI, it is possible manually configure Sunshine by
editing the `conf` file in a text editor. Use the examples as reference.

            Similarly, for constant quality encoding, you will simply save bitrate by choosing a slower preset.
