How to use podman without sudo?

I use podman with oci-containers but is there a better approach?
I have to do sudo to go into podman, at user level there is no container
I discovered this in my research which is interesting

There’s no NixOS module for rootless containers if that’s what you’re looking for. Making your own systemd units that execute as other users isn’t particularly hard, though.

What exactly are you looking to do with these containers?
