install
Pick your apps. One is enough.
Tick what you want and copy the command. Each app's installer asks for its database, the shared account database and an admin, then starts the service. The requirements are short.

Every app has its own default port, so all of them fit on one host. The installer creates the admin you answered; with several apps it is the same admin everywhere, because the accounts live in one Shared ioSuite database.
Then put the apps behind your reverse proxy for HTTPS (Caddy, nginx, HAProxy or a Cloudflare Tunnel), and every app updates itself from Settings › Server.
