Run this command to install gulp and its packages:
npm install gulp gulp-rimraf gulp-autoprefixer gulp-svg-sprites
After that you only need to run gulp command and it will execute these tasks:
- Clean the dist/ directory
- Autoprefix the styles in css/s.scss
- Generate a SVG sprite from the SVGs inside assets/svg/
- Copy all the necessary files inside dist/
And finally you'll have the result in dist/ folder.
