            Provider are the <Icon name="heart" color="red" /> of Fredy. We're supporting multiple Provider such as
            Immowelt, Kalaydo etc. Select a provider from the list below.
            <br />
            Fredy will then open the provider's url in a new tab.
          </p>
          <p>
            You will need to configure your search parameter like you would do when you do a regular search on the
            provider's website.
            <br />
            When the search results are shown on the website, copy the url and paste it into the textfield below.
            <br />
            <span style={{ color: '#ff0000' }}>
              If you chose Immoscout as a provider, make sure to also add the scrapingAnt apiKey to the config.json.
              (See readme)
            </span>
            <br />
            <span style={{ color: '#ff0000' }}>
              Do not forget to sort the results by date before copying the url to Fredy, so that Fredy always captures
              the latest search results.
