 - `cat <src>`: Read a file from the database and write to stdout.
 - `put <dst>`: Read from stdin and write to the database path `<dst>`.
+- `remote-add <name> <connstr>`: Add a remote configuration from a connection string.
+- `remote-rm <remote-id>`: Remove a remote configuration by ID.
+- `remote-ls`: List remote configurations (`id`, `name`, `active/inactive`, redacted URI).
+- `remote-export <remote-id>`: Export the stored connection string by remote ID.
+- `remote-set <remote-id> <connstr>`: Replace the stored connection string by remote ID.
+- `remote-activate <remote-id>`: Activate a remote configuration by ID.
 - `init-settings [file]`: Create a default settings file.
