+# Rust/Tokio Server
+
+This directory contains an [Tokio](https://tokio.rs/) server running on Unikraft.
+
+## Set Up
+
+To run this example, [install Unikraft's companion command-line toolchain `kraft`](https://unikraft.org/docs/cli), clone this repository and `cd` into this directory.
+
+## Run and Use
+
+Use `kraft` to run the image and start a Unikraft instance:
+
+```bash
+kraft run --rm -p 8080:8080 --plat qemu --arch x86_64 -M 512M .
+```
+
+If the `--plat` argument is left out, it defaults to `qemu`.
+If the `--arch` argument is left out, it defaults to your system's CPU architecture.
+
+Once executed, it will open port `8080` and wait for connections.
+To test it, you can use `curl`:
+
+```bash
+curl localhost:8080
+```
+
+You should see a "Bye, World!" message.
+
+## Inspect and Close
+
+To list information about the Unikraft instance, use:
+
+```bash
+kraft ps
+```
+
+```text
+NAME         KERNEL                          ARGS     CREATED         STATUS   MEM   PORTS                   PLAT
+stoic_nyota  oci://unikraft.org/base:latest  /server  23 minutes ago  running  488M  0.0.0.0:8080->8080/tcp  qemu/x86_64
+```
+
+The instance name is `stoic_nyota`.
+To close the Unikraft instance, close the `kraft` process (e.g., via `Ctrl+c`) or run:
+
+```bash
+kraft rm stoic_nyota
+```
+
+Note that depending on how you modify this example your instance **may** need more memory to run.
+To do so, use the `kraft run`'s `-M` flag, for example:
+
+```bash
+kraft run --rm -p 8080:8080 --plat qemu --arch x86_64 -M 1024M .
+```
+
+## `kraft` and `sudo`
+
+Mixing invocations of `kraft` and `sudo` can lead to unexpected behavior.
+Read more about how to start `kraft` without `sudo` at [https://unikraft.org/sudoless](https://unikraft.org/sudoless).
