## Instalando manipuladores de exceções customizados

Você pode adicionar manipuladores de exceção customizados com <a href="https://www.starlette.io/exceptions/" class="external-link" target="_blank">a mesma seção de utilidade de exceções presentes no Starlette</a>

Digamos que você tenha uma exceção customizada `UnicornException` que você (ou uma biblioteca que você use) precise lançar (`raise`).
