The main tasks that you can do right now are:

* [Help others with questions in GitHub](#help-others-with-questions-in-github) (see the section above).
* [Review Pull Requests](#review-pull-requests) (see the section above).

Those two tasks are what **consume time the most**. That's the main work of maintaining FastAPI.

 * Direct ACEs are evaluated first in order. The SID of the user performing

 * ACE and <i>any</i> of the desired access bits match bits in the access

Because of this, **FastAPI** itself provides an alternative API documentation (using ReDoc), which you can access at [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc):
