 ## GSMArena
+In order to use the script an account (trial is suffiecient) at scraperapi.com is needed. Then look up your API key at the dashboard at scraperapi.com and enter it in the source code in AttributeSpyder.py under `client = ScraperAPIClient('xxx')` instead of the `xxx`.
+You can also remove the code dependent on scraperapi but this will result in gsmarena.com rate-limiting and blocking you requests.
