## Usage
**src/css/**
Generated css and min.css files. No need to touch this. 

**src/fonts/**
Include your font files here

**src/img/**
Include your image files here

**src/js/**
Edit the `script.js` and add your own javascript code there. Gulp will merge the vendor javascripts `bootstrap.js`, `jquery.js` and `script.js` to a `main.js` & `main.min.js`

**src/less/**
Whole styling goes here. `_bootstrap.less` to control the bootstrap includes, `variables.less` to override and manage less variables and `main.less` to include the extern less files. If you add or delete less files you need to remove them from `main.less`, too. 

**src/vendor**
Vendor files, installed over bower.
