## ⚙️ Current Behavior Currently, the repository lacks a template for environment variables. New contributors have to hunt through the code or documentation to figure out which keys (like GOOGLE_API_KEY) are required to run the application locally. ## 🚀 Proposed Improvement I suggest adding a .env.example file to the root directory. This file will serve as a secure, non-sensitive template that lists all required environment variables with placeholder values. ## 🔍 Why It’s Needed Standardization: It follows industry best practices for open-source projects. Onboarding: It significantly reduces the setup time for new developers. Security: It provides a clear guide on what needs to be configured in a local .env file without accidentally exposing real keys. ## 🧩 Possible Implementation Create a .env.example file in the root with the following content: Plaintext # TalkHeal Environment Variables Template # Copy this file to a new file named '.env' and fill in your actual values. # Google Gemini API Key - Get one at https://aistudio.google.com/ GOOGLE_API_KEY=your_api_key_here ## ✅ Checklist [x] I’ve reviewed existing issues to ensure this isn’t a duplicate.
