 # Introduction
 
-⚠️ This material is based on unstable crates. It worked at the time of writing but following it today may not result in compiling code! However, it can be used as inspiration for getting started with Rust on Espressif.

 ## Content of this material
 
 This is Ferrous Systems' *Embedded Rust on Espressif* training material. It is divided into two workshops: introductory and advanced. The introductory trail will introduce you to basics of embedded development and how to make the embedded board interact with the outside world - reacting to commands and sending sensor data.
 
 The advanced course takes it from there to dive deeper into topics like interrupt handling, low-level peripheral access and writing your own drivers.

 ## The board
 
-An [Espressif Rust Board](https://github.com/esp-rs/esp-rust-board) is mandatory[^note] for working with this book - emulators like QEMU are not supported.

 The board design and images, pin layout and schematics can be also found in this repository.
 
 If you subscribed to one of the trainings, a board will be provided to you directly by Espressif.
 Some exercises also require wireless internet access.

 Our focus lies primarily on the [ESP32-C3](https://www.espressif.com/en/products/socs/esp32-c3) platform, a [RISC-V](https://riscv.org/) based microcontroller with strong IoT capabilities, facilitated by integrated Wi-Fi and Bluetooth 5 (LE) functionality as well as large RAM + flash size for sophisticated applications. A substantial amount of this course is also applicable for Xtensa the other architecture Espressif uses, in particular the [ESP32-S3](https://www.espressif.com/en/products/socs/esp32-s3). For low-level access the general principles apply as well, but actual hardware access will differ in various ways - refer to the technical reference manuals ([C3](https://www.espressif.com/sites/default/files/documentation/esp32-c3_technical_reference_manual_en.pdf), [S3](https://www.espressif.com/sites/default/files/documentation/esp32-s3_technical_reference_manual_en.pdf)) or [other available technical documents](https://www.espressif.com/en/support/documents/technical-documents)  as needed.

-Basic Rust like [The Rust Book](https://doc.rust-lang.org/book/) Chapters 1 - 6, Chapter 4 Ownership does not need to be fully understood.
