+### Development Setup
+
+1. Clone the repository: `git clone git@github.com:UI5/linter.git ui5-linter`
+2. Navigate to the repository and install dependencies: `cd ui5-linter && npm install`
+3. Build the server: `npm run build`
+    * While developing, you may use `npm run build-watch` to automatically rebuild the server on code changes. Make sure to restart the server in your MCP client to get your changes!
+4. Link it globally: `npm link` - this makes the `ui5mcp` command available globally
+
+In your MCP client, use the following configuration to reference the local server:
+
+```json
+{
+  "mcpServers": {
+    "ui5mcp": {
+      "type": "stdio",
+      "command": "ui5mcp",
+      "args": []
+    }
+  }
+}
+```
