+**NOTE**: This project uses OAuth2 to enable Google login. By default, it’s disabled for convenience.  
+If you’d like to use Google login, follow [this guide](https://support.google.com/googleapi/answer/6158849?hl=en) to create your credentials. Then make the following changes:
+
+**In the backend .env:**
+
+```bash
+GOOGLE_CLIENT_ID=<your_google_client_id>
+GOOGLE_CLIENT_SECRET=<your_google_client_secret>
+USE_OAUTH=True
+```
+**In the root .env:**
+
+```bash
+GOOGLE_CLIENT_ID=<your_google_client_id> # exclude the '.apps.googleusercontent.com' part
+VITE_USE_OAUTH=true
+```
+
