Description
The project currently lacks a .env.example file, which can cause confusion for new contributors trying to run the app locally. Without knowing which environment variables are required (e.g., PORT, MONGO_URI, JWT_SECRET), setup becomes guesswork.
Suggested Fix
Add a .env.example file in the root directory with placeholder values for required variables. This will improve developer onboarding and prevent misconfiguration.
Additional context
Happy to open a PR for this if approved!
