# Configuration via YAML file

> Learn how to configure CodeRabbit using a YAML file for advanced customization.

In this guide, we will cover the configuration using a YAML file. For the complete list of available options, see the [Configuration Reference](/reference/configuration). For ready-to-use examples tailored to specific frameworks and languages, see [Configuration Examples](/configuration/example).

<Info>
  Move existing UI configuration to a YAML file?

  Use the `@coderabbitai configuration` command on any PR to get the current configuration in a YAML format. You can then copy the configuration to a `.coderabbit.yaml` file in the root of your repository.

## Configure CodeRabbit using a YAML File

`.coderabbit.yaml` configuration file must be located in the root of the repository. The configuration present in the feature branch under review will be automatically detected and used by CodeRabbit for that review.

### Example Configuration

```yaml .coderabbit.yaml theme={null}
# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json
language: "en-US"
early_access: false
reviews:
  profile: "chill"
  request_changes_workflow: false
  high_level_summary: true
  poem: true
  review_status: true
  review_details: false
  auto_review:
    enabled: true
    drafts: false
chat:
  auto_reply: true
```

## Configuration Options

The configuration file supports numerous options for customizing CodeRabbit's behavior. For the complete list of available configuration options and their descriptions, see the [configuration reference](/reference/configuration#reference).

Please note that code reviews commence with new pull requests or incremental commits to existing pull requests once the CodeRabbit app is installed. Should you have any questions or require assistance, visit the [support page](/support).

## Shared configuration

<Warning>
  Shared configuration is not recommended, as it may expose sensitive
  configuration details. Please use [Central
  Configuration](/configuration/central-configuration) for managing
  configurations across multiple repositories and [Configuration
  Inheritance](/configuration/configuration-inheritance) for reusing
  configurations across different layers.
</Warning>

If you are self-hosting CodeRabbit in an air-gapped environment, you can use the shared configuration feature to share the configuration across multiple repositories.

To use shared configuration, you need to:

1. Create a `.coderabbit.yaml` file and host it in a location that is publicly accessible (e.g., a web server, a public GitHub Gist).
2. Create a `.coderabbit.yaml` file in the root of your repository with the following content:

```yaml theme={null}
remote_config:
  url: "https://your-config-location/.coderabbit.yaml"
```
