-The decoders are specified by their ID, as shown in the
-.B \-\-version
-output. In addition to the
-.B \-S
-option, all protocol decoders that are used in a stack, must also be specified
-(together with their options, if any) using the
-.B \-P
-parameter.
+The
+.B sigrok\-cli
+application can automatically assign logic channels to decoder inputs
+in their strict channel index order (by means of the
+.B auto_index
+keyword), or can automatically assign logic channels to decoder inputs
+when their names match (case insensitive match,
+.B auto_names
+keyword). Users need to explicitly request this assignment, the default
+behaviour is to not automatically assign any signals.
+.sp
+Example:
+.sp
+ $
+.B "sigrok\-cli \-i <file.sr>"
+.br
+.B " \-P ieee488:assign_channels=auto_names"
+.br
+.sp
+When multiple decoders are specified in the same
+.BR -P
+option, they will be stacked on top of each other in the specified order.
