+# WAMR (Wasm Micro Runtime) Image
+
+This directory contains the definition for the `unikraft.org/wamr` image.
+
+To run this image, [install Unikraft's companion command-line toolchain `kraft`](https://unikraft.org/docs/cli) and then you can run:
+
+```
+kraft run unikraft.org/wamr:bc762f
+```
+
+Once executed you will get a "Hello, World!" message and one regarding a memory address.
