# Includes

The `includes` section of YAML configuration files lets you specify additional YAML files to be merged into the current configuration. This lets you organize complex configurations into smaller, manageable files and include them as needed.

These files are identified as a list of filenames and can include relative or absolute paths. If a path isn't specified as absolute, it will be treated as relative to the file that includes it.

## Usage

The following example demonstrates how to include additional YAML files using relative path references. This is the file system path structure:

```
├── fluent-bit.yaml
├── inclusion-1.yaml
└── subdir
    └── inclusion-2.yaml
```

{% hint style="info" %}
Environment variables aren't supported in includes section. The path for each file must be specified as a literal string.
{% endhint %}

You can reference these files in `fluent-bit.yaml` as follows:

```yaml
includes:
  - inclusion-1.yaml
  - subdir/inclusion-2.yaml
```

Ensure that the included files are formatted correctly and contain valid YAML configurations for seamless integration.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fluentbit.io/manual/administration/configuring-fluent-bit/yaml/includes-section.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
