Contributing
The patterns and testcases are synced from the PHP repo. If you find a bot/spider/crawler user agent that crawlerdetect fails to detect, please submit a pull request with the regex pattern and a testcase to the upstream PHP repo.
Failing that, just create an issue with the user agent you have found, and we'll take it from there :)
