 ### Getting Started
 
-- Install Node.js (I'd suggest using `nvm`)
-- Install your preferred package manager (doesn't have to be `pnpm`, I'm just using it as an example)
-- Run `pnpm install` to install dependencies
-- Run `pnpm demo` to test your changes at first glance
-- Run `pnpm test` to run tests
-- Don't forget to run `pnpm format` && `pnpm lint` before commiting your changes
+1. Pick and install a Node version manager
+   * Linux/OSX - [nvm](https://github.com/nvm-sh/nvm)

+   * Windows 7 - [nodist](https://github.com/nullivex/nodist)
+   * Win/Lin/OSX - [volta](https://volta.sh)
