I use bitwarden and the setup was fairly standard with the helper script. I use my own isolated proxy for all my services so that was already built. I haven’t used vaultwarden but if anyone that has used both can tell me the differences I could maybe help out.
If it’s the same then after installing docker, creating a vaultwarden user, adding said user to docker group, and creating your vaultwarden directories, all that’s left is to curl the install script and answer the questions it asks.
