Remove sudo from install guide?

It's certainly odd that you have to go out of your way to setup Docker on Linux so that it doesn't need sudo. Nonetheless, it might be best to presume that user of this repo, whatever the OS, doesn't need sudo. Totally worth avoiding. If there are any malware problems in the associated Docker images...

Thanks for your feedback.

I removed the sudo prefix from the docker commands.

The user can be added to the docker group.
