+# Introduction
+
+This is the exercise book accompanying the Embedded Rust Workshop.
+The Workshop provides exercises for Embedded Rust which run on the
+[BBC microbit v2](https://microbit.org/new-microbit/).
+
+For this exercises, you only require the following hardware:
+
+- The [microbit v2](https://microbit.org/new-microbit/).
+- A Micro-USB cable to power the microbit while also connecting it to your computer.
+
+This little educational board has everything we need to teach you the practical part of embedded
+Rust, including:
+
+- A 5x5 LED matrix.
+- The LSM303AGR on-board motion sensor.
+- A serial connection accessible by a USB-CDC device
+
+This device has even more features and external connectivity, and you can find all
+of this information of the [microbit website](https://tech.microbit.org/hardware/).
+
+## Goals
+
+After working through this exercises, you should have the following skills:
+
+- Extract relevant information from datasheets and/or schematics for firmware development.
+- Understand and work in embedded code using the the [`embassy`](https://embassy.dev/) asynchronous
+  runtime, which includes using the `async` / `await` syntax.
+- Schedule concurrent tasks using `embassy`.
+- Work with some components of a provided HAL (or BSP).
+- Using [`embassy-time`](https://docs.rs/embassy-time/latest/embassy_time/) to perform delays and
+  periodic operations or measure elapsed time.
+- Writing drivers for simple sensors
+
+However, these exercises do not replace or provide a good theoretic foundation and it also does
+not teach general Rust programming. Low-level aspects like working with registers and details about
+system boot are are intentionally skipped. The next section provides some further material
+recommendations to address this.
+
+## Further Materials
+
+If you are a beginner in Rust, it is strongly recommended to work through the [Rust book](https://doc.rust-lang.org/book/) or work
+through some other method of your choice to learn the general language.
+
+The following materials might be valuable for you as well:
+
+- [The embassy book](https://embassy.dev/book/) provides additional information and documentation
+  about the embassy asynchronous run-time.
+- [The Rusty bits](https://www.youtube.com/@therustybits) provides excellent visual resources
+  about various embedded Rust aspects.
+- [The Ferrous Systems Rust Training slides](https://rust-training.ferrous-systems.com/latest/slides/)
+  provide high-quality slides about various topics, including embedded Rust and aspects like
+  system boot and peripheral access crates.
+
+## Preparation
+
+We are going to start with the preparation of the software tools in the [next chapter](./preparation.md).

+# Preparation
+
+## Rust and `cargo`
+
+The first thing required is the Rust compiler and the `cargo` build and dependency management
+tool. The Rust installation includes the `cargo` tool, so all you need to do is install
+Rust by going to the [Rust website](https://rust-lang.org/tools/install/) and following the operating
+system specific instructions.
+
+After you have done this, you can verify your installation by running:
+
+```console
+cargo version
+```
+
+Normally, you would have to also install the `thumbv7em-none-eabihf` toolchain and some other
+useful tools, but this is performed automatically for you through the `rust-toolchain.toml`
+file in the code directory.
+
+## `flip-link` linker
+
+You need to install a special linker called `flip-link` for building the software. Run
+the following command in the terminal:
+
+```console
+cargo install flip-link
+```
+
+## Flasher tool `probe-rs`
+
+Next, you need some software which allows flashing the microbit v2 via the USB interface.
+We are going to use the `probe-rs` tool, which is well integrated into the Rust ecosystem:
+
+The `probe-rs` website has [install instructions](https://probe.rs/docs/getting-started/installation/)
+for various operating systems. Follow these, and then test your installation using the following
+command
+
+```console
+probe-rs --version
+```
+
+## USB permission setup (Linux only)
+
+Finally, if you are on Linux, you need to perform some steps related to `udev` to avoid permission
+issues. `probe-rs` has a [page with steps you can follow](https://probe.rs/docs/getting-started/probe-setup/).
+
+## IDE
+
+You can use any IDE of your choice which has good [Rust Analzyer Support](https://rust-analyzer.github.io/).
+
+If you are looking for a solid graphical IDE, [VS Code](https://code.visualstudio.com/<35;127;26M)
+is an excellent choice. Make sure to install the [rust-analyzer plugin](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer) as well.
+
+## Testing everything
+
+Now you should have everything you need to build and flash some application to the board.
+You can flash a test application now to test everything. We provide some test applications for you.
+
+Connect the board to your computer using a Micro-USB cable. Make sure that your cable also
+supports the data interface and is not power-only.
+
+Go into the `code/app` directory.
+
+Now, you can run the following command to build and flash a blinky application:
+
+```console
+cargo run --bin blinky
+```
+
+On the console, you should see an output like this:
+
+```console
+❯ cargo run --bin blinky
+   Compiling rust-app v0.1.0 (/home/muellerr/Rust/rust-embedded-workshop/code/app)
+    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.17s
+     Running `probe-rs run --chip nRF52833_xxAA --allow-erase-all target/thumbv7em-none-eabihf/debug/blinky`
+      Erasing ✔ 100% [####################]  48.00 KiB @  35.81 KiB/s (took 1s)     Finished in 3.55s
+-- microbit v2 Blinky application --
+```
+
+If `probe-rs` can not detect anything, make sure that (a) the board is connected through USB, and
+(b) the `udev` rules were setup properly if you are on Linux.
+
+If everything goes right, you should see the LED in the top-left corner blinking with a frequency of 1 second.
+If this is the case, congratulations, you have built and flashed an embedded Rust app and you made if through
+the preparation chapter successfully!
+
+In the [first exercise](./blinky-exercise.md), you are going to build most parts of a blinky.
