nvm (Node Version Manager) is used to install whichever Node.js version you need for the specific project. Once you choose your Node.js version for a project, we suggest that you write it in .nvmrc, so that all other developers can use that exact same version and you don't have to hardcode it in your CI.
Yarn is installed globally in the container and set up to use the same Node.js you are using through nvm.
