+## 🚀 **How to Use**
+
+### **Step 1: Set Up API Keys**
+Add to your `.env` file (at least one required):
+```bash
+# Google Custom Search (Recommended)
+GOOGLE_SEARCH_API_KEY=your_key_here
+GOOGLE_SEARCH_ENGINE_ID=your_engine_id_here
+
+# Bing Search API
+BING_SEARCH_API_KEY=your_bing_key_here
+
+# SerpAPI (Good for development)
+SERPAPI_API_KEY=your_serpapi_key_here
+
+# Brave Search API
+BRAVE_SEARCH_API_KEY=your_brave_key_here
+
+# You.com Search API
+YOUCOM_API_KEY=your_youcom_key_here
+
+# DuckDuckGo (Free, no key required)
+```
+
+### **Step 2: Test the Implementation**
+```bash
+# Run the comprehensive test
+npx tsx src/lib/server/webSearch/test.ts
+```
+
+### **Step 3: Use in Chat**
+Send messages like:
+- `🌐 Using web search who is david parnas`
+- `web search latest AI news`
+- `what is quantum computing`
+- `tell me about blockchain`
