After I moved from WordPress to Hugo , I was missing a commenting system. Actually, I never did receive that many comments when using WordPress, but I still want to give folks the ability to leave comments. I was looking for a simple, self-hosted solution that would work with my VPS. My VPS provider does not permit root access, so that was an additional restriction. My VPS does support using a “rootless” version of Docker, and I learned that Remark42 would work with it.
