 > [!TIP]
 > For package managers such as `pipenv` and `poetry`, you need to use the `pip` YAML value. For example, if you use `poetry` to manage your Python dependencies and want {% data variables.product.prodname_dependabot %} to monitor your dependency manifest file for new versions, use `package-ecosystem: "pip"` in your `dependabot.yml` file.
