@fellowgeek Yup that's because I use a private docker repository for now. I am working right now on publishing to dockerhub. Would have done it today but had other imperatives. Will be fixed in the next few days.

@fellowgeek I have added instructions in the README but I still have some small QoL improvements for the self-hosting experience to do before considering this closable.
