On WSL2 don't put the project files into `/mnt/c/` as file I/O speeds are extremely slow. Instead, run everything in the Linux system and use `cp` to move files over to `/mnt/c/` as needed. Use `cmd.exe` with these instructions rather than PowerShell.
::: :::
Chocolatey is recommended and used for the following instructions. You can manually install each of these applications and add them to your `PATH` if you don't want to use Chocolatey.
1. [Install Chocolatey](https://chocolatey.org/install)
2. Open `cmd.exe` as **Administrator**
3. Run the following `choco` commands:
```shell
choco install cmake --installargs 'ADD_CMAKE_TO_PATH=System'
choco install ninja gperf python git

### Zephyr™ ARM SDK ### Toolchain Installation

<TabItem value="raspberryos">
Because Raspberry OS (Raspbian) runs on the same architecture (but different ABI) as the keyboard MCUs,
the operating system's installed [cross compilers](https://docs.zephyrproject.org/latest/getting_started/toolchain_other_x_compilers.html) can be used to target the different ABI.
First, the cross compiler should be installed:
```sh
sudo apt install gcc-arm-none-eabi
```
Next, we'll configure Zephyr™ with some extra environment variables needed to find the cross compiler by adding the following to `~/.zephyrrc`:
```sh
export ZEPHYR_TOOLCHAIN_VARIANT=cross-compile
export CROSS_COMPILE=/usr/bin/arm-none-eabi-
