# Development - Contributing

First, you might want to see the basic ways to [help FastAPI and get help](help-fastapi.md).

## Developing

If you already cloned the [fastapi repository](https://github.com/fastapi/fastapi) and you want to deep dive in the code, here are some guidelines to set up your environment.

### Install requirements

Create a virtual environment and install the required packages with [`uv`](https://github.com/astral-sh/uv):

	margin-top: 8em;
	margin-bottom: 4em;
}

.notification {
	font-size: 1.2em;
	margin: 0.2em;
}

.searchButtonBox {
	margin-top: 1em;
}
