Nowadays I'd be surprised at people having trouble setting up ReasonML tooling. It should be just:

- npm install --global bs-platform # (you need to ensure you have write access to the global install path)

- Fire up VSCode

- Install the reason-vscode extension

- Run `bsb -init my-project -theme react-hooks` (assuming you want to scaffold a new ReasonReact project)
