+    NOTE: Skipfish uses dictionary-based probes and will not run until you
+    have selected and made a copy of a dictionary for it to use.
+
+    Please read consult dictionaries/README-FIRST carefully to make the right
+    choice. This step has a profound impact on the quality of scan results
+    later on.
