 **Step 1: Clone and install**
 
 ```bash
-git clone https://github.com/lyonzin/knowledge-rag.git
-cd knowledge-rag
+# Clone to your home directory
+git clone https://github.com/lyonzin/knowledge-rag.git ~/knowledge-rag
+cd ~/knowledge-rag
 pip install -r requirements.txt
 ```
 
-Or install from PyPI into an existing project:
-```bash
-pip install knowledge-rag
-```
+> **Windows users**: `~/knowledge-rag` becomes `C:\Users\YourName\knowledge-rag`
 
 **Step 2: Configure Claude Code**
 
-Run this command to add the MCP server:
+From inside the cloned folder, run:
 
 ```bash
-# Windows
-claude mcp add knowledge-rag -- cmd /c "cd /d C:\path\to\knowledge-rag && python -m mcp_server.server"
-
-# Linux / macOS
-claude mcp add knowledge-rag -- python -m mcp_server.server --cwd /path/to/knowledge-rag
+cd ~/knowledge-rag
+claude mcp add knowledge-rag -s user -- python -m mcp_server.server
 ```
 
-Or manually add to `~/.claude.json`:
+That's it. Claude Code now knows about your RAG server.
