 == Methods
 

-=== Control methods
-These methods are available if the daemon is started anonymously (without an explicit `-u USERNAME`).
-Requests are sent to `/org/asamk/Signal`; requests related to individual accounts are sent to
-`/org/asamk/Signal/_441234567890` where the + dialing code is replaced by an underscore (_).
-Only `version()` is activated in single-user mode; the rest are disabled.
+=== SignalControl interface
+
+These methods are available if the daemon is started in multi-account mode (without an explicit `-a ACCOUNT`).
+The exported `/org/asamk/Signal` object provides a SignalControl interface, with methods to manage accounts.
+Individual accounts are exported as separate objects and provide a Signal interface, that's described below.
+e.g. `/org/asamk/Signal/\_441234567890` where the + dialing code is replaced by an underscore (_).
