+The *g:ycm_quiet_messages* option
+
+When this option is set, YCM will suppress any diagnostic items that would
+otherwise be displayed that match any of the rules provided. The value is a 
+dictionary which should be set to something like:
+>
+  let g:ycm_quiet_messages = {
+        \ "!level":  "errors",
+        \ "regex":   '\m\[C03\d\d\]' }

+This option is part of the Syntastic compatibility layer; if the option is not
+set, YCM will fall back to the value of the 'g:syntastic_quiet_messages'
+option before using this option's default.
+
+See |syntastic_quiet_messages| for more details, as this option follows that
+one. Currently, only "level" and "regex" rules are supported; unsupported rule 
+types are ignored.
+
+As in Syntastic, there are also filetype-specific variants of this option, which 
+will be used in preference to this if they exist. 
+They are named |'ycm_<filetype>_quiet_messages'|.
