+# NodeJS 18
+
+This directory contains the definition for the `unikraft.org/node:18` image starting a simple HTTP server.
+
+To run this image, [install Unikraft's companion command-line toolchain `kraft`](https://unikraft.org/docs/cli) and then you can run:
+
+```console
+kraft run -p 8080:8080 unikraft.org/node:18
+```
+
+Query the server using:
+
+```console
+curl localhost:8080
+```
+
+You will get a `Hello, World!` message.
