}

Contributing

If you find a bot/spider/crawler user agent that CrawlerDetect fails to detect, please submit a pull request with the regex pattern added to the $data array in Fixtures/Crawlers.php and add the failing user agent to tests/crawlers.txt.

Failing that, just create an issue with the user agent you have found, and we'll take it from there :)
