Improvement: Add Environment Variables Setup Instructions

[fladmorty1987]

Description

It would be helpful to include instructions on how to set up environment variables for the project, especially if any are required for the deployment or local development. This will make it easier for new contributors or users to get started without running into configuration issues.

Suggested Updates

1. Add a section in the README: Create a new section titled 'Environment Variables' or 'Configuration' before the 'Getting Started Locally' section.
2. Provide examples: Include specific examples of any environment variables needed, and how to create an .env file if necessary.

This improvement will enhance user experience and lead to a smoother setup process.
