### HTML

Updating HTML pertains mainly to SVG icon paths. 
It's now recommended to use inline SVG icons. 

```html
<svg class="bx--accordion__arrow" width="8" height="12" viewBox="0 0 8 12" fill-rule="evenodd">
  <path d="M0 10.6L4.7 6 0 1.4 1.4 0l6.1 6-6.1 6z"></path>
</svg>
```

But if you're going to make use of carbon-icons.svg, it's recommended to use the sprite svg file locally in your project. 

Update `<use xlink:href>` to a local path of bluemix-icons.svg, which should look something like this:

```html
<svg class="bx--accordion__arrow">
  <use xlink:href="/carbon-icons/bluemix-icons.svg#chevron--right"></use>
</svg>
```

For more details on installing and using bluemix-icons, see install and usage guidelines docs here.

### SCSS

The `_accordion.scss` file is now located at `src/components/accordion/_accordion.scss`. You'll need to update any `@import` statements for this file to reflect this change.

**New**: 
```scss
@import 'path_to_node_modules/carbon-components/src/components/accordion/accordion';
```

**Old**: 
```scss
@import 'path_to_node_modules/@console/bluemix-components/src/components/accordion/accordion';
```
