.SYNOPSIS
    Setup script for the Gemini Echo application.

.DESCRIPTION
    This script is designed to initialize and configure the necessary environment settings for the Gemini Echo system.
    It may perform tasks such as environment variable configuration, installation of required modules, and any preparatory 
    steps to ensure that dependencies and system settings are correctly established prior to running the main application.
    
.PARAMETERS

.NOTES
    File Path: ./setup.ps1
    This script automates the setup of your Gemini Echo development environment by checking for required software,
    creating a virtual environment, and installing dependencies. Tailor these instructions further to suit additional project needs.

.EXAMPLE
    To execute this setup script, open a PowerShell prompt and run:
        PS> .\setup.ps1
        
    Ensure that you have the necessary permissions and that your execution policy is set appropriately to allow script execution.
