+#### Raspberry Pi and other architectures

+If you are running Docker in a Raspberry Pi (that has an ARM processor) or any other architecture, you can create a `Dockerfile` from scratch, based on a Python base image (that is multi-architecture) and use Uvicorn alone.

+In this case, your `Dockerfile` could look like:

+```Dockerfile
+FROM python:3.7
