+### Prompt Engineering
 
-The model expects prompts in the following format:
+**Recommended Format:**

-AI: Jawaban dari AI <|endoftext|>
+User: [Your question or instruction in Indonesian]
+AI: [Expected response starts here]
 ```
 
-## ⚠️ Limitations
+**Examples of Effective Prompts:**
+- `User: Jelaskan cara kerja fotosintesis dengan bahasa sederhana\nAI:`
+- `User: Buatkan kode Python untuk menghitung luas lingkaran\nAI:`
+- `User: Apa perbedaan antara demokrasi dan republik?\nAI:`
+
+## ⚠️ Limitations and Considerations
+
+**Knowledge Limitations:**
+- **Training Data Cutoff**: Knowledge is limited to the training datasets, primarily Wikipedia-based information
+- **Factual Accuracy**: Generated responses may not always be factually accurate or up-to-date
+- **Real-time Information**: Cannot access current events or real-time data
 
-- **Knowledge Base**: The base model was trained primarily on Wikipedia data: `indonesian-nlp/wikipedia-id` by [Cahya](https://huggingface.co/cahya), providing general factual knowledge but limited real-world conversational patterns
-- **Training Data Scope**: Current fine-tuning focuses on general instruction-following and Q&A rather than natural daily conversations
-- **Conversational Style**: Responses may feel formal or academic due to the Wikipedia-based foundation and instruction-tuned nature
-- **Model Size**: Relatively small (124M Parameters), which may limit complex reasoning capabilities
-- **Factual Accuracy**: Responses are generated based on training data and may not always be factually accurate or up-to-date
-- **Language Optimization**: Best performance is achieved with Indonesian language inputs
-- **Response Consistency**: May occasionally generate repetitive or inconsistent responses
+**Technical Limitations:**
+- **Model Size**: With 124M parameters, complex reasoning capabilities are limited compared to larger models
+- **Context Length**: Limited context window may affect very long conversations
+- **Language Specialization**: Optimized primarily for Indonesian; other languages may produce suboptimal results
 
-## 🚀 Future Improvements
+**Response Characteristics:**
+- **Formality**: Responses may occasionally sound formal due to Wikipedia-based training data
+- **Consistency**: May generate repetitive patterns or inconsistent information across sessions
+- **Cultural Nuances**: While trained on Indonesian data, may miss subtle cultural references or regional variations
 
-For enhanced conversational naturalness, consider:
-- **Conversational Dataset Training**: Fine-tuning with Indonesian daily conversation datasets
-- **Lighter LoRA Configuration**: Using more efficient LoRA parameters for conversation-specific training
-- **Multi-turn Dialogue**: Training on multi-turn conversation data for better context handling
-- **Informal Language Patterns**: Incorporating colloquial Indonesian expressions and casual speech patterns
+## 🚀 Future Development Roadmap
+
+**Short-term Improvements:**
+- Fine-tuning with more diverse conversational datasets
+- Integration of current Indonesian news and cultural content
+- Specialized domain adaptations (education, healthcare, business)
