Documentation Inconsistency Regarding Virtual Environment Setup for Windows

[rayyush]

In the "Getting Started" section of the repository, the instructions for setting up a virtual environment on Windows seem to be incomplete. While the command for activating the virtual environment on Windows is provided as .\venv\Scripts\activate, there is no mention of the need to install virtualenv globally on the system before running this command.

In order to avoid potential confusion for users unfamiliar with the setup process, it would be helpful to add a step before creating the virtual environment.
