[npm-run-all](https://github.com/mysticatea/npm-run-all) is a cross-browser approach to running npm tasks in series (`-s`) or parallel (`-p`). Rather than using a platform specific method to run scripts (e.g. `&&`), npm-run-all will work on all platforms and supports using Yarn if running with Yarn. I made a guess as to whether certain scripts should be run in series or parallel but feel free to change if my choices aren't optimal.
