It may seem a bit tricky, comparing to good-old-way method, when you include libs from CDNs and add some custom JSs & CSSs to doc's head.

But, I promise, you'll fall in love with npm-way when you get used to it ^-)

Installation

Install node & npm

You must first ensure that Node.js and NPM are installed on your machine.

Download and install version for your system.

Then, install theme's dependencies

When you're good with node & npm, the only remaining step is to install theme's package dependencies. You'll find a package.json file in the root of your directory structure. The default package.json file includes everything you need to get started.

To install dependencies open system command line, cd to project's dir & run:

npm install

Usage

Check theme's README.md
