 A hub server for MCP servers.
 
-## Installation
+## Usage
+
+1. Create a configuration file named `mcp_settings.json` with your MCP server settings:
+
+```json
+{
+  "mcpServers": {
+    "time-mcp": {
+      "command": "npx",
+      "args": ["-y", "time-mcp"]
+    },
+    "sequential-thinking": {
+      "command": "npx",
+      "args": [
+        "-y",
+        "@modelcontextprotocol/server-sequential-thinking"
+      ]
+    }
+  }
+}
+```
+
+2. Run MCP Hub using Docker:
+
+```bash
+docker run -p 3000:3000 -v ./mcp_settings.json:/app/mcp_settings.json samanhappy/mcphub
+```
+
+This will:
+- Map port 3000 from the container to your local machine
+- Mount your local configuration file into the container
+- Start the MCP Hub server
+
+3. The server will be available at `http://localhost:3000/sse`
