@donkeyblam good question. I suppose there's general stuff to read out there, but given the vanishingly low cost of getting into it (e.g. a $5/month commodity VPS) it's something I just learned by doing. I've written up a whole bunch of howtos which give some guidance on VPSs stuff, too: https://tech.oeru.org - a good starting point would probably be the Bit/VaultWarden howto. It's a hugely useful service: https://tech.oeru.org/setting-your-own-bitwarden-password-manager-and-vaultwarden-sync-server
