+Install bknd as a dependency:
+<InstallBknd />
+
+## Serve the API & static files
+The `serve` function of the Node adapter makes sure to also serve the static files required for
+the admin panel.
+
+``` tsx
+// index.js
+import { serve } from "bknd/adapter/node";
+
+// if the configuration is omitted, it uses an in-memory database
+/** @type {import("bknd/adapter/node").NodeAdapterOptions} */

+      }
+   }
+};
+
+serve(config);
+```
+For more information about the connection object, refer to the [Setup](/setup) guide.
+
+Run the application using node by executing:
+```bash

+Any bknd app instantiation accepts as connection either `undefined`, a connection object like

+```ts

+import { Connection } from "bknd/data";

+class CustomConnection extends Connection {

+const connection = new CustomConnection();

 ## Installation
 To install **bknd**, run the following command:
 <InstallBknd />
