start a node.js service

I am attempting to follow the setup instructions for the node.js service, blueimp-file-upload, found here:

https://github.com/blueimp/jQuery-File-Upload/wiki/Setup

Specifically, I'm working through these steps under Using jQuery File Upload (UI version) with Node.js:

You can install the sample Node.js upload service on your server via npm:

npm install blueimp-file-upload-node

You can start the service by running the following command:

./node_modules/blueimp-file-upload-node/server.js

I have completed the first step (the installation of npm), but I do not understand what is meant by running the "./node_modules/..." command. It is not considered valid syntax in Windows' command prompt, nor the Node.js-specific command prompt, even when prefixed with npm.
