Can't find docker-compose.yml

I’m currently running docker on an Ubuntu 18.04 machine and using the setup instructions provided by BW but when I get to the part where I have to run “sudo ./ start” it gives the following message:

ERROR: .FileNotFoundError: [Errno 2] No such file or directory: ‘/home//bwdata/docker/docker-compose.yml’

Do I have to manually create this file?

No, why are you using sudo though?
