-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.

+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**
