 ### NVM
 
 To set up nvm, the Node Version Manager, follow the instructions listed [here](https://github.com/nvm-sh/nvm#readme). We recommend [setting up their shell integration](https://github.com/nvm-sh/nvm#deeper-shell-integration) as well, so you can automatically switch to the correct Node version when working on this project. Otherwise, ensure you run `nvm use`. This project requires the "current" supported release series of Node.
