 object.  You can use this to attach some helpful info about _why_ the
 command is being run, if it makes sense for your use case.
 
+If `stdio` is set to anything other than `'inherit'`, then the result/error
+will be decorated with `stdout` and `stderr` values.  If `stdioString` is
+set to `true`, these will be strings.  Otherwise they will be Buffer
+objects.

 Returned promise is decorated with the `stdin` stream if the process is set
 to pipe from `stdin`.  Writing to this stream writes to the `stdin` of the
 spawned process.
 
 #### Options
 
-- `stdioString` Boolean, default `false`.  Return stdio/stderr output as
