crawler_detect.isCrawler()
# true if crawler user agent detected
```
#### Output the name of the bot that matched (if any)
```Python
from crawlerdetect import CrawlerDetect
crawler_detect = CrawlerDetect()
crawler_detect.isCrawler('Mozilla/5.0 (compatible; Sosospider/2.0; +http://help.soso.com/webspider.htm)')
# true if crawler user agent detected
crawler_detect.getMatches()
# Sosospider
```
### 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 array in `providers/crawlers.py` 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 :)
