+# ParaKasa Geliştirme Planı (Revize Edildi)
+
+**Vizyon:** Proje, tek bir çatı altında iki farklı uygulama gibi çalışacaktır.
+
+## 1. Web Sitesi (Public)
+- Herkese açık kurumsal web sitesi.
+- Ürünler, kategoriler ve iletişim bilgileri sergilenecek.
+- Veriler Yönetim Panelinden (CMS) çekilecek.
+
+## 2. Yönetim Paneli (Private)
+- Sadece firma yetkililerinin giriş yapabileceği kapalı devre sistem.
+- **Fonksiyonlar:**
+    - **CMS:** Web sitesinin içeriğini (ürünler, slider, metinler) yönetme.
+    - **ERP (İç Yönetim):** Stok takibi, gelir/gider hesapları, sipariş yönetimi.
+- **Durum:** Bu bölümün tasarımı ve akışı tamamen baştan kurgulanacak. Şimdilik mevcut haliyle donduruldu.
+
+---
+
+## Mevcut Durum (Tamamlananlar)
+- [x] Kullanıcı Yönetimi (Admin Ekle/Sil).
+- [x] Temel Site Ayarları (Başlık, İletişim).
+- [x] Ürün Yönetimi (Temel CRUD).
+- [x] Kategori Yönetimi (Arayüz hazır, veritabanı bekleniyor).
