This is one more episode that has been requested many times. So the goal is to make a page on our backend from which we can control some aspects of our site and our theme. Luckily October CMS already has this functionality out baked in, all you have to do is configure that page and implement the data into your site or your theme.

In this video I'm going to show you how to create theme settings or even site options for your October CMS site.

October CMS - Theme Settings

Drupal uses .yml files for dealing with libraries (css and js), this is great. But the setup of those files in your theme isn't exactly intuitive, but it's not hard either.

In this tutorial you will learn how to register your theme and add css and JavaScript files to your theme.

### Code used in this video

**endymion.info.yml**

 ```yml 
name: Endymion
description: Drupal 8 Starter Theme

libraries:
  - endymion/global-css
  - endymion/global-js

    theme:
      css/style.css: {}

  js:
    js/main.js: {}
