 ## Building locally
 
- - Install [Node.js](https://nodejs.org/en/) version 6.3.1 or later.
+ - Install [Node.js](https://nodejs.org/en/) version 8.11.3 and npm version 6.1.0
  - Install dependencies:
-   - For node versions up to and including 9, install local dependencies with `npm install`.
-   - For node versions 10 and later, install [Yarn](https://yarnpkg.com/lang/en/docs/install/) and use `yarn install`.
+   - If you are using nvm (recommended) running `nvm use` will automatically choose the right node version for you.
  - Install gulp globally with `npm install -g gulp-cli`.
  - Build the project to the `./dist/` folder with `gulp build`.
  - Optionally, to rebuild on file changes, run `gulp dev`.
