# How to add a configuration file for Code Health

Using a YAML File to Configure Typo

You can add a configuration file named `".typoapp.yaml"` or `".typoapp.yml"`  to the root of your repository to customize how Typo works. This file is a simple way to define settings for your projects directly in your code.

The `".typoapp.yaml"` or `".typoapp.yml"` file must be present in your base/target branch for Typo to apply the configuration to its analysis and reports
