 _microbit_ contains everything required to get started with the use of Rust to create firmwares for the fabulous [BBC micro:bit][] microcontroller board. This little board has everything and a kitchen sink built-in, even a capable debugging interface, so all that one needs to get going with programming this device is:
 
-* A BBC micro:bit board
+* A BBC micro:bit board (at the moment v1 only)
 * A computer (macOS and Linux work perfectly, [Windows tested as well](http://flames-of-code.netlify.com/blog/rust-microbit-windows/))
 * A bit of open source software
 
 Some very preliminary examples of using this crate can be found [here in this repo][examples] or [here on my blog][myblog].
 
 A guide to embedded development with Rust on the _microbit_ using this crate can be found in the [MicroRust book][microrust].
 
+The [BBC micro:bit][] and this crate is compatible with the fantastic tooling
+provided by the [knurling] project. If you haven't done so already, installing
+`probe-run` and playing around with the examples is highly recommended:
+```bash
+# cargo install probe-run
+# cargo run --release --example led_blocking
+   Compiling microbit v0.8.0
+    Finished release [optimized + debuginfo] target(s) in 15.39s
+     Running `probe-run --chip nRF51822_xxAA target/thumbv6m-none-eabi/release/examples/led_blocking`
+  (HOST) INFO  flashing program (1.95 KiB)
+  (HOST) INFO  success!
+RTT logs not available; blocking until the device halts..
