5. Execute the following commands:

   python setup.py build

   python setup.py install

6. If the install is successful, you will not see any errors on the terminal.

Download the crawler.py file from the repo. This file is used to crawl a given site. I have listed a few use cases below:

The following command will display the total number of links found on a particular website after crawling:
