3. Install the requirements

4. Run the scrapers:

   # sync
   (env)$ python script.py headless
   
   # parallel with multiprocessing
   (env)$ python script_parallel_1.py headless
   
   # parallel with concurrent.futures
   (env)$ python script_parallel_2.py headless
   
   # concurrent with concurrent.futures (should be the fastest!)
   (env)$ python script_concurrent.py headless
   
   # parallel with concurrent.futures and concurrent with asyncio
   (env)$ python script_asyncio.py headless

5. Run the tests:

   (env)$ python -m pytest test/test_scraper.py
   (env)$ python -m pytest test/test_scraper_mock.py
