+    ### 📝 Kullanım İpuçları:
+    - **Prompt**: Detaylı ve açıklayıcı olun (örn: "photorealistic", "8k", "detailed" ekleyin)
+    - **Negative Prompt**: İstemediğiniz özellikleri ekleyin
+    - **Steps**: 25-30 arası optimal (daha fazla = daha yavaş)
+    - **Guidance Scale**: 7-8 arası genelde en iyi sonuçları verir
+
