+**Never commit real tokens to Git or any public repository!**
+
+### 🔧 الإعداد الصحيح | Correct Setup
+
+#### 1. نسخ ملف البيئة | Copy Environment File
+```bash
+cp .env.example .env
+```
+
+#### 2. تحرير ملف .env | Edit .env File
+```bash
+# افتح الملف في محرر النصوص

+
+# أو
+code .env
+```
+
+#### 3. إضافة الرموز الحقيقية | Add Real Tokens
+```bash
+# استبدل هذه القيم بالرموز الحقيقية
+HF_TOKEN_READ=hf_your_real_read_token_here
+HF_TOKEN_WRITE=hf_your_real_write_token_here  
+HF_TOKEN_FINE_GRAINED=hf_your_real_fine_grained_token_here
+```
+
+### 🛡️ قواعد الأمان | Security Rules
+
+#### ✅ افعل | Do
+- احفظ الرموز في ملف `.env` فقط
+- استخدم ملف `.gitignore` لمنع رفع `.env`
+- استخدم رموز مختلفة للبيئات المختلفة
+- راقب استخدام الرموز بانتظام
+- احذف الرموز غير المستخدمة
+
+#### ❌ لا تفعل | Don't
+- لا ترفع ملف `.env` إلى Git
+- لا تضع الرموز في الكود مباشرة
+- لا تشارك الرموز عبر البريد الإلكتروني
+- لا تستخدم نفس الرمز لجميع المشاريع
+- لا تترك الرموز في ملفات التوثيق
+
+### 🔄 إدارة الرموز | Token Management
+
+#### إنشاء رموز جديدة | Create New Tokens
+1. اذهب إلى https://huggingface.co/settings/tokens
+2. انقر على "New token"
+3. اختر النوع المناسب:

+## Usage
+
+```python
+from transformers import AutoModel, AutoConfig
+
+# Load the model
+model = AutoModel.from_pretrained("path/to/model", trust_remote_code=True)
+config = AutoConfig.from_pretrained("path/to/model")
+
+# Use for inference or further training
+outputs = model(input_ids)
+```
+
+## Retraining
+
+This model can be used as a student model for incremental training:
+
+```python
+# Load as existing student for further distillation
+existing_student = "path/to/this/model"
+# Add new teachers and continue training
+```

+## التحديات التقنية المتوقعة والحلول
+
+### 1. تحدي معالجة البيانات الطبية الكبيرة
+
+#### المشكلة:
+- ملفات DICOM كبيرة الحجم (100MB+ لكل ملف)
+- قواعد بيانات تصل إلى عدة تيرابايت
+- تنسيقات ��عقدة ومتنوعة
+
+#### الحل المقترح:
+```python
+class MedicalDataOptimizer:
+    def __init__(self):
+        self.compression_ratio = 0.3
+        self.streaming_buffer_size = 1024 * 1024 * 100  # 100MB
+
+    async def optimize_dicom_loading(self, dicom_path: str):
+        """تحسين تحميل ملفات DICOM"""
+        # ضغط البيانات أثناء التحميل
+        # تحميل metadata أولاً

+
+    async def stream_large_dataset(self, dataset_name: str):
+        """تدفق قاعدة البيانات الكبيرة"""
+        # تقسيم إلى chunks قابلة للإدارة
+        # تحميل chunk → معالجة → حذف → التالي
+        pass
+```
+
+### 2. تحدي دقة التشخيص الطبي
+
+#### المشكلة:
+- متطلبات دقة عالية جداً (>95%)
+- حساسية للأخطاء في التشخيص
+- تنوع كبير في الحالات الطبية
+
+#### الحل المقترح:
+```python
+class MedicalAccuracyValidator:
+    def __init__(self):
+        self.min_diagnostic_accuracy = 0.95
+        self.min_sensitivity = 0.90

+        # حساب uncertainty estimation
+        # تحديد مستوى الثقة
+        # تحذير عند انخفاض الثقة
+        pass
+```
+
+### 3. تحدي التوافق مع المعايير الطبية
+
+#### المشكلة:
+- الامتثال لمعايير HIPAA
+- حماية خصوصية البيانات الطبية
+- متطلبات الأمان العالية
+
+#### الحل المقترح:
+```python
+class MedicalComplianceManager:
+    def __init__(self):
+        self.encryption_standard = 'AES-256'
+        self.anonymization_level = 'full'
+
