-  - If you're using [NVM](https://github.com/creationix/nvm#installation) (recommended), `nvm use` will ensure that the right version is installed.
+- Install the current LTS version of [Node.js](https://nodejs.org)
+  - If you are using [nvm](https://github.com/creationix/nvm#installation) (recommended) running `nvm install` will install the latest version and running `nvm use` will automatically choose the right node version for you.
 - Install [Yarn v3](https://yarnpkg.com/getting-started/install).
 - Run `yarn install` to install dependencies and run any required post-install scripts.
 - Run `yarn simple-git-hooks` to add a [Git hook](https://github.com/toplenboren/simple-git-hooks#what-is-a-git-hook) to your local development environment which will ensure that all files pass linting before you push a branch.
