-Set up a specific client integration (creates API key and writes config to the client's config file):
-
 ```sh
-routstrd clients add --opencode
+routstrd clients add --opencode --pi-agent --claude-code  # multiple integrations
-routstrd clients add --claude-code

+## Remote Mode
+
+When `daemonUrl` is configured, commands connect to a remote daemon instead of a local one:
+- Client names are suffixed with the last 7 chars of your npub
+- All requests are automatically NIP-98 signed using your local nsec
+- Local-only commands (`onboard`, `start`, `restart`, `mode`, `logs`, `service`) are disabled
+
 ## Pi Integration
 
 When `routstrd onboard` runs, it automatically configures a `routstr` provider in `pi`'s `models.json` with an OpenAI-compatible base URL and API key. This allows pi (the AI coding agent) to use Routstr providers seamlessly.
