# additional_paths

> The `additional_paths` key defines file paths to copy onto your infrastructure

## Overview

```yaml alto.yml theme={null}
...
additional_paths:
  - "../data/"
...
```

The `additional_paths` key contains a list of paths to copy onto your infrastructure.

<Note>By default, the working directory (i.e., the directory with your YAML configuration
file) is copied onto your infrastructure. The `additional_paths` key can be used to
copy folders and/or files *outside* of your working directory onto your infrastructure.</Note>

You probably won't need to use this key that often.
