Pydantic has an official <a href="https://docs.pydantic.dev/latest/migration/" class="external-link" target="_blank">Migration Guide</a> from v1 to v2.

It also includes what has changed, how validations are now more correct and strict, possible caveats, etc.

# Full Stack FastAPI Template { #full-stack-fastapi-template }

Templates, while typically come with a specific setup, are designed to be flexible and customizable. This allows you to modify and adapt them to your project's requirements, making them an excellent starting point. 🏁

You can use this template to get started, as it includes a lot of the initial set up, security, database and some API endpoints already done for you.

## Вход { #login }

Убедитесь, что у вас уже есть аккаунт **FastAPI Cloud** (мы пригласили вас из списка ожидания 😉).

Затем выполните вход:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

## Деплой { #deploy }

Теперь разверните приложение одной командой:

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...
