+#### Bot Detection
+
+Some sites (including Kleinanzeigen and ImmoScout24) implement bot detection to prevent scripts from scraping their sites. Flathunter includes support for running a headless Chrome browser to simulate human requests to the websites. **For crawling Kleinanzeigen and ImmoScout24, you will need to install Google Chrome**
+
 #### Captchas
 
 Some sites (including ImmoScout24) implement a Captcha to avoid being crawled by evil web scrapers. Since our crawler is not an evil one, the people at [2Captcha](https://2captcha.com) and [Imagetyperz](https://imagetyperz.com/) provide services that help you solve them. You can head over to one of those services and buy some credit for captcha solving. You will need to install the API key for your captcha-solving account in the `config.yaml`. Check out `config.yaml.dist` to see how to configure `2Captcha` or `Imagetyperz` with Flathunter. **At this time, ImmoScout24 can not be crawled by Flathunter without using 2Captcha/Imagetyperz. Buying captcha solutions does not guarantee that you will get past the ImmoScout24 bot detection (see [#296](https://github.com/flathunters/flathunter/issues/296), [#302](https://github.com/flathunters/flathunter/issues/302))**.
