 patterns we can import such data of arbitrary formats as date or datetime.
 
 csv2sql uses the [Timex](https://github.com/bitwalker/timex) library to parse date/datetime.
-In order to specify custom patterns for date or datetime use the `--custom-date-patterns` or `--custom-datetime-patterns` arguments
-followed by a string having one or more patterns separated by `;`
+You can specify multiple custom patterns for date or datetime as a string having one or more patterns separated by `;`
 
 When using the Web UI for csv2sql enter these pattern strings in the config page under "Custom date patterns" or "Custom datetime patterns".
 
 The patterns should be compatible with Timex directives specified [here](https://hexdocs.pm/timex/Timex.Format.DateTime.Formatters.Default.html#module-list-of-all-directives).
