-## Catatan:
+---
-- Starter project ini dibuat berbantukan AI
-- Kembangkan project dari starter yang sudah disediakan, jangan membuat dari awal.
-- Untuk koordinat bisa ditambah/kurangi angka tertentu agar tidak memunculkan koordinat rumah masing-masing, data awal tetap dari GPS.

+- **PENGEMBANGAN**: Proyek ini dikembangkan dari *starter project* yang disediakan dan tidak dibuat dari nol.
+- **PRIVASI KOORDINAT**: Untuk alasan keamanan/privasi, angka koordinat GPS dapat dimodifikasi sedikit agar tidak menunjukkan lokasi rumah pribadi secara presisi.
