:bulb: Description:
This Udemy Downloader tool allows users to download Udemy courses, including DRM-protected content. However, decryption keys are required to download DRM-encrypted courses. This tool is in WIP (Work in Progress) status, and the code is provided as-is. Windows is the primary development environment, but Linux is also supported. Mac is untested.
:warning: Disclaimer: Downloading Udemy courses violates their Terms of Service, and the author is not responsible for any legal or account-related consequences.
:gear: Features:
Download Udemy courses (including DRM-protected ones).
Support for downloading videos, captions, quizzes, and assets.

:hammer_and_wrench: Requirements:
Before using this tool, ensure you have the following installed on your system (manual installation required):

:memo: Setup Instructions:
Download the repository and navigate to the folder.
