Expand README with Data Instructions

[Jinxxxx1234]

Summary

The README describes the project and usage but does not clearly specify how to obtain the dataset or where it should be placed locally.

Proposed Improvement

• Add a "Data" section to the README.

• Include:

  • Dataset source link
  • Instructions for downloading
  • Expected directory structure (e.g., data/raw/)
  • Any preprocessing steps required before running the notebook

Rationale

Clear data instructions improve usability and make the project easier to reproduce for collaborators and reviewers.
