+
+### Adding files
+
+If you want to add new super-awesome `.js` files, just add them. Deemix uses ES6 synthax, so you'll probably need to export some functions or variables from your new file. Files that will export and import nothing will be ignored by the bundler (rollup).
+
+If you want to add new mega-awesome `.scss` (style) files, you need to import them in the main `style.scss` file. The `.scss` files **must** all start with an underscore _, except for the `style.scss` file.
