Installation

Adapt Config.xml

The xml file contains all the items to be observed. All items should be enclosed within the tag. Each item on the other hand should be enclosed within an tag, as shown in the following:

<?xml version="1.0" encoding="utf-8"?>
<data>
    <selenium-options>
        <headless-mode>
            True
        </headless-mode>
    </selenium-options>
    <item name="flamingo-ball">
        <path>
            https://www.amazon.de/ballonfritz%C2%AE-Flamingo-Ballon-Riesenballon-Geburtstagsgeschenk/dp/B07D24S144/ref=sr_1_5?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91
            keywords=flamingo+ballon qid=1561379051 s=gateway sr=8-5
        </path>
    </item>
</data>

If you are going to base your config file on example_config.xml do not forget to rename it to config.xml. The given chromedriver in bin/chromedriver is actually the one for macos. Depending on your operating system you might have to replace it by the correct one, see Chromedriver Chromium.
