🧪 Local Development Setup

0. Fork the repo Fork the repo locally

1. Clone the repository

   git clone https://github.com/yourusername/dms.git
   cd dms

📌 Notes

• Uses Google Drive API for storing files – ensure proper OAuth scopes and token handling.
• Cookies and tokens may have issues on secure browsers with strict policies (e.g., Brave).
• Frontend and backend must be hosted under the same or compatible subdomains for cookie handling.
