# Config files

There are two configuration files that you'll need: a `prism_project.py` file for managing your Python environment, and a `profile.yml` file to establish connections to an external data warehouse. They're covered in more detail next.

* [`prism_project.py`](https://docs.runprism.com/v0.1.9/fundamentals/config-files/prism_project.py)
* [`profile.yml`](https://docs.runprism.com/v0.1.9/fundamentals/config-files/profile-yml)
