The Docker guide is what people should follow for self-hosting. It mentions it can be used for cloud providers at the top. Maybe we should also mention that you can use the image for self-hosting.

Tho, people using Docker would probably know that they can run it locally or wherever they want 🤔 that is kinda of the point of Docker.
