 Set the value associated with *secret* (specified by its UUID) to the value
 Base64-encoded value *base64* or Base-64-encoded contents of file named
-*filename*.
+*filename*. Using the *--plain* flag is together with *--file* allows to use
+the file contents directly as the secret value.

 Note that *--file* and *base64* options are mutually exclusive.
