Add Comprehensive Docstrings to Codebase

**Is your feature request related to a problem? Please describe.**
Currently, the codebase lacks comprehensive docstrings, making it difficult for developers to understand the purpose and functionality of various methods and classes. This can lead to confusion and increased time spent on code review and debugging.

**Describe the solution you'd like**
I propose adding detailed docstrings to all methods and classes in the codebase. These docstrings should follow a consistent format and provide clear explanations of the parameters, return values, and any exceptions raised.

**Describe alternatives you've considered**
Creating a separate documentation file is an alternative solution, but it might not be as effective as embedding docstrings directly within the code. Docstrings are more accessible to developers, making it easier for them to understand and maintain the code.

**Additional context**
Adding comprehensive docstrings will improve code readability and maintainability, making it easier for both current and future developers to work with the codebase.
