+## Recommendation for New Contributors
+
+If you are contributing for the first time, we strongly recommend starting with **Level 1** issues.  
+These tasks are beginner-friendly and help you understand the project structure, contribution workflow, and coding style before moving to more advanced issues.
+
+Once you feel comfortable, you can gradually try Level 2 and Level 3 tasks.
