+## Usage
+
+### RAG System
+
+```python
+from datasets import load_dataset
+
+# Load logic documents
+ds = load_dataset("tellang/FateFusion-Logic-Docs")
+
+# Store in vector DB for RAG
+for doc in ds['train']:
+    # Add to ChromaDB, Pinecone, etc.
+    pass
+```
+
+### System Prompt Reference
+
+```python
+# Load specific domain logic
+bazi_logic = ds['train'].filter(lambda x: x['domain'] == 'bazi')
+jami_logic = ds['train'].filter(lambda x: x['domain'] == 'jami')
+
+# Use as system prompt context
+system_prompt = f"""
+당신은 점술 전문가입니다.
+다음 로직을 참조하여 해석하세요:
+
+[사주 로직]
+{bazi_logic[0]['content']}
+
+[자미두수 로직]
+{jami_logic[0]['content']}
+"""
+```
+
+### Knowledge Base
+
+```python
+# Build knowledge base for Q&A
+knowledge_base = {}
+for doc in ds['train']:
+    domain = doc['domain']
+    if domain not in knowledge_base:
+        knowledge_base[domain] = []
+    knowledge_base[domain].append(doc['content'])
+```
