## Ask Questions { #ask-questions }

You can <a href="https://github.com/fastapi/fastapi/discussions/new?category=questions" class="external-link" target="_blank">create a new question</a> in the GitHub repository, for example to:

* Ask a **question** or ask about a **problem**.
* Suggest a new **feature**.

**Note**: if you do it, then I'm going to ask you to also help others. 😉
