# Using Dataclasses { #using-dataclasses }

FastAPI is built on top of **Pydantic**, and I have been showing you how to use Pydantic models to declare requests and responses.

But FastAPI also supports using [`dataclasses`](https://docs.python.org/3/library/dataclasses.html) the same way:

 * the fact that the problem reporter has/should not have information about the calling context and hence cannot provide
 * an expressive source hint for the model problem. Instead, the source hint is configured by the model builder before
 * it delegates to other components that potentially encounter problems. Then, the problem reporter can focus on
 * providing a simple error message, leaving the donkey work of creating a nice model problem to this component.

## Docs

First, make sure you set up your environment as described above, that will install all the requirements.

### Docs live

During local development, there is a script that builds the site and checks for any changes, live-reloading:

<div class="termy">

```console
$ python ./scripts/docs.py live
