-      'NOFX is an AI-powered cryptocurrency trading bot that uses large language models (LLMs) to make trading decisions on futures markets.',
+      'NOFX is an open-source AI-powered trading operating system for cryptocurrency and US stock markets. It uses large language models (LLMs) like DeepSeek, GPT, Claude, Gemini to analyze market data and make autonomous trading decisions. Key features include: multi-AI model support, multi-exchange trading, visual strategy builder, backtesting, and AI debate arena for consensus decisions.',
 
-    faqSupportedExchanges: 'Which exchanges are supported?',
+    faqHowDoesItWork: 'How does NOFX work?',
-    faqSupportedExchangesAnswer:
+    faqHowDoesItWorkAnswer:
-      'Binance Futures, Hyperliquid, and Aster DEX are supported. More exchanges coming soon.',
+      'NOFX works in 5 steps: 1) Configure AI models and exchange API credentials; 2) Create a trading strategy (coin selection, indicators, risk controls); 3) Create a "Trader" combining AI model + Exchange + Strategy; 4) Start the trader - it will analyze market data at regular intervals and make buy/sell/hold decisions; 5) Monitor performance on the dashboard. The AI uses Chain of Thought reasoning to explain each decision.',
 
     faqIsProfitable: 'Is NOFX profitable?',
     faqIsProfitableAnswer:
-      'AI trading is experimental and not guaranteed to be profitable. Always start with small amounts and never invest more than you can afford to lose.',
+      'AI trading is experimental and NOT guaranteed to be profitable. Cryptocurrency futures are highly volatile and risky. NOFX is designed for educational and research purposes. We strongly recommend: starting with small amounts (10-50 USDT), never investing more than you can afford to lose, thoroughly testing with backtests before live trading, and understanding that past performance does not guarantee future results.',
 
-    faqMultipleTraders: 'Can I run multiple traders simultaneously?',
+    faqSupportedExchanges: 'Which exchanges are supported?',
-    faqMultipleTradersAnswer:
+    faqSupportedExchangesAnswer:

+    faqHowAIDecides: 'How does the AI make trading decisions?',
+    faqHowAIDecidesAnswer:
+      'The AI uses Chain of Thought (CoT) reasoning in 4 steps: 1) Position Analysis - reviews current holdings and P/L; 2) Risk Assessment - checks account margin, available balance; 3) Opportunity Evaluation - analyzes market data, indicators, candidate coins; 4) Final Decision - outputs specific action (buy/sell/hold) with reasoning. You can view the full reasoning in decision logs.',
