grunt-setup

Requirements:

• Node.js (tested with version 5.5.0)
• npm (tested with version 3.4.1)
• Ruby (tested with version 2.3.0)
• Sass (tested with version 3.4.21)

cd into the grunt directory and run:

npm install

To start the watching, run:

grunt watch

The package.json file contains only the version and name fields. Those are actually required.

{
  "version": "0.0.1",
  "name": "grunt-sass-cssmin"
}

You may want to at least add the description, repository and license fields. Otherwise npm will spew out warnings.

More about the package.json file can be found here.
