 ## Custom formatting
 
-...
+Sometimes the phone number has footprints but is used with a different formatting. This is a problem because for example if we search for "+15417543010", we'll not find web pages that write it that way : "(541) 754–3010". So the tool use a (optional) custom formatting given by the user to find further and more accurate results.
