+## Local Environment Setup
+Both the client and server folders require a .env file for environment-specific configurations. Below are the instructions for setting up these files.
+
+### Server Folder (.env)

+   ```bash
+   # Server Configuration
+   PORT=5000
+
+   # PostgreSQL Database
+   DATABASE_URL=postgres://postgres:${your_pg_password}@127.0.0.1/algohub
+   PG_HOST="127.0.0.1"
+   PG_USER="postgres"
+   PG_PASSWORD= # Add your PostgreSQL password here
+   PG_DATABASE=algohub
+
+   # Google OAuth Credentials
+   CLIENT_ID=1088957184358-6vg9gfngftpc85443sb1e55v4m1l4cb6.apps.googleusercontent.com

+   ```
+
+### Client Folder (.env)
+You must create a .env file in the client folder to store environment variables. Use the following template to set up your .env file:
+   ```bash
+   # Google auth Ceredentials
+   REACT_APP_CLIENT_ID=1088957184358-6vg9gfngftpc85443sb1e55v4m1l4cb6.apps.googleusercontent.com
