     The numbering can be suppressed by using the -n option.
 
+    By default tablizer shows a header containing the names of each column.
+    This can be disabled using the --no-headers option. Be aware that this
+    only affects tabular output modes. Shell, Extended, Yaml and CSV output
+    modes always use the column names.
+
     By default, if a pattern has been speficied, matches will be
     highlighted. You can disable this behavior with the -N option.
