	resp, err := http.DefaultClient.Get("https://www.hackerone.com")
	if err != nil {
		log.Fatal(err)
	}
	data, _ := io.ReadAll(resp.Body) // Ignoring error for example

	wappalyzerClient, err := wappalyzer.New()
	fingerprints := wappalyzerClient.Fingerprint(resp.Header, data)
	fmt.Printf("%v\n", fingerprints)
