Build ReadTheDocs for this repo

[sonnhfit]

Problem:
The current GitHub repository lacks comprehensive documentation, hindering the ease of understanding, contributing, and utilizing the project. To address this gap, it is essential to establish a documentation framework using ReadTheDocs.

Objective
The primary goal is to set up ReadTheDocs for the GitHub repository, ensuring that the documentation is automatically generated and consistently updated with changes in the codebase.

Key Tasks:

1. Configuration Setup:

Configure ReadTheDocs to link with the GitHub repository.
Establish a connection that triggers documentation builds automatically upon changes to the repository.

2. Documentation Structure:

Create a structured documentation outline covering project overview, installation, usage, contribution guidelines, and code reference.
Utilize Sphinx or equivalent tools to generate documentation from inline comments and docstrings.

3. Integrate with Continuous Integration (CI):
   Incorporate ReadTheDocs into the project's CI/CD pipeline to ensure that documentation stays in sync with the latest codebase.
   Verify that the CI process doesn't break due to documentation build issues.
