 * STM32
 * Raspberry Pi Pico
 * Linux, Mac OS X or Windows
+* Espressif ESP32
 * WASM (WebAssembly)
 
 We provide examples for a subset of hardware that we ensure works and that are relevant for IoT.
 
+## Minimal Quickstart
+
+```
+rustup update 
+cargo install probe-run
+```
+
 ## Example applications
 
 An overview of the examples can be found in the [documentation](https://book.drogue.io/drogue-device/dev/examples.html).
