How to install this Gatsby theme

The most up-to-date docs on installing a Gatsby theme can be found on the Gatsby website, but here's a summary using this theme as an example:

# or

npm install --save theme

Then edit your gatsby-config.js file:

module.exports = {
  plugins: [

      resolve: 'theme',
      options: {
        basePath: '/'
      }
    }
  ]
};
