title: "Private Configuration File"
description: "Configure advanced Pangolin settings using the privateConfig.yml file for enterprise features"
---

The `privateConfig.yml` file provides advanced configuration options for enterprise deployments. This file is mounted at `config/privateConfig.yml` in your Docker container.

<Note>
The private configuration file is only used on enterprise deployments. If you're using Pangolin Community, refer to the [main configuration file documentation](/self-host/advanced/config-file) instead. The private config file is not required.
</Note>

## Setting up your `privateConfig.yml`

Here's a basic example with common settings:

```yaml title="private-config.yml"
flags:
  use_org_only_idp: false

branding:
  app_name: "My Company Portal"
  hide_auth_layout_footer: false
```

## Reference

This section contains the complete reference for all configuration options in `private-config.yml`.
