@omerBotenski1987 thanks for the suggestion. Could you please provide more context on the error you're seeing?

In general I'd avoid telling users to escalate privileges, and instead redirect them to the Docker docs, which recommend adding users to the docker Unix group on their Docker host.

Sure. I tried to run this docker on a ubuntu server hosted on AWS, and when I ran the compose command I got the following error: ERROR: Couldn't connect to Docker daemon at http+docker:https://localhost - is it running?

OK that makes sense if your user wasn't inside the group I mentioned. However, I'd recommend following the instructions at https://docs.docker.com/install/linux/linux-postinstall/ instead of giving users the false impression they need to run arbitrary commands using sudo. It is assumed that users have correctly set up their environment prior to fiddling with this project.

How about linking the page above under the "requirements" title of the README instead? For example:

Host setup

• Docker Engine version 17.05+ and a properly configured host (add link)
