-> This tutorial is available as a Jupyter notebook [here](https://github.com/Future-House/paper-qa/blob/main/docs/tutorials/settings_tutorial.ipynb).
-
-This tutorial aims to show how to use the `Settings` class to configure `PaperQA`.
-Firstly, we will be using `OpenAI` and `Anthropic` models, so we need to set the `OPENAI_API_KEY` and `ANTHROPIC_API_KEY` environment variables.
-We will use both models to make it clear when `paperqa` agent is using either one or the other.
-We use `python-dotenv` to load the environment variables from a `.env` file.
-Hence, our first step is to create a `.env` file and install the required packages.
-
 ```python
 # fmt: off
 # Create .env file with OpenAI API and Anthropic API keys
