+এই অ্যাপটি সরাসরি WinGo লাইভ মার্কেটের সাথে কানেক্ট করে Big/Small সিগন্যাল দেখায়।
+
+## ব্যবহার:
+1. Flutter SDK এবং Android Studio ইনস্টল করুন।
+2. প্রোজেক্টটি Android Studio-তে খুলুন।
+3. Terminal-এ `flutter pub get` রান করুন।
+4. Android Studio থেকে “Build APK” ক্লিক করুন।
+5. তৈরি APK ফোনে ইনস্টল করুন।
+
+## লক্ষ্য:
+- প্রতি ৫ সেকেন্ডে নতুন রাউন্ড চেক করে signal আপডেট হবে।
+- Big = Green, Small = Red।
