TL; DR

$ cd hypno.cat
$ npm install
...
$ npm run build
...
$ cp docs path/to/docs

Content quick description

Build is performed by Gulp, take a look at the gulpfile.js

Sources for both javascript and CSS are stored in the src folder.

For javascript, files from src/scripts are concatenated into a single file (home.js)

For CSS, SaSS preprocessor takes care of producing the css file (home.css) from src/styles

Vendors script and styles are copied nearly as is from src/vendors

src/resources is just a backup storage for assets
