**Linux**: Check your Linux distribution package manager (example below). If it's not there, follow the instructions on [https://code.visualstudio.com/docs/setup/linux](https://code.visualstudio.com/docs/setup/linux).
**Windows**: *Do* install the optional components of the [C++ build tools package](https://visualstudio.microsoft.com/visual-cpp-build-tools/). The installation size may take up to 2 GB of disk space.
**All**: Open VS Code and look for [Rust Analyzer](https://marketplace.visualstudio.com/items?itemName=matklad.rust-analyzer) in the marketplace (bottom icon in the left panel). Then install it.
Install version v0.8.0 of the [`cargo-flash`](https://crates.io/crates/cargo-flash) and [`cargo-embed`](https://crates.io/crates/cargo-embed) subcommands, as well as the [`cargo-binutils`](https://crates.io/crates/cargo-binutils) set of subcommands and the [`cargo-bloat`](https://crates.io/crates/cargo-bloat) subcommand using the following Cargo commands:
The workshop git repository contains custom crates that help you with flashing and debugging the workshops. Depending on the workshop you're attending, you need to install all or some of them.
#### Beginner workshop
Change to the `tools` folder and run these commands *from different terminals so they'll run in parallel*:
```console
$ cd embedded-trainings-2020/tools
$ cargo install --path usb-list
$ # in a new terminal, for parallelization
$ cargo install --path dongle-flash
$ # in a new terminal, for parallelization
$ cargo install --path serial-term
$ # in a new terminal, for parallelization
$ cargo install --path change-channel
```
Leave the processes running in the background.
#### Advanced workshop
Change to the `tools` folder and run these commands:
- in the installer check the "add Python 3.x to PATH" box
- also run the "Disable path length limit" action at the end, if you are on Windows 10 and the option is displayed to you

**All**: Open a terminal and install [nrfutil](https://github.com/NordicSemiconductor/pc-nrfutil) as follows. *If you are familiar with python, it is advised to do this in a [virtual environment](https://docs.python.org/3/library/venv.html).*
Some nRF52840 devices, specially older revisions, may have parts of their Flash memory locked. To unlock the memory use the [`nrf-recover`](https://crates.io/crates/nrf-recover) tool.
This is only relevant to the nRF52840 Development Kit. First connect the nRF52840 DK to your PC using micro-USB J2 (as done before) then run the following commands:
