Good point, I will add a readme in the next update.
Scraping and using an API are very different. APIs are typically hosted on a separate domain and present you information in a text format that is designed for code to easily and efficiently read.
Scraping, on the other hand, is going onto the main website itself and manually digging through all of the HTML to get information. That is not only really slow, inefficient, and time-consuming to implement, but if the website host ever decides to change it's layout it becomes obsolete and needs to be completely rewritten.
