`BeautifulSoup` is a Python library that is used to parse HTML and XML documents. It creates parse trees that are helpful in extracting the data easily. It sits atop an HTML or XML parser, providing Pythonic idioms for iterating, searching, and modifying the parse tree.

Here is an example of how to use `BeautifulSoup` to parse an HTML document and extract some data:

```python
from bs4 import BeautifulSoup

# Open the HTML file and create a Beautiful Soup object
with open("document.html") as f:
  soup = BeautifulSoup(f, "html.parser")
```

In this project, we are going to understand how to create a simple web scraper in Python.
