 > Svelte implementation of the [Carbon Design System](https://github.com/carbon-design-system)
 
-## Getting Started
+## Getting started
 
-`carbon-components-svelte` can be installed as a development dependency.
+Install `carbon-components-svelte` as a development dependency.
 
 ```bash
 yarn add -D carbon-components-svelte
+# OR
+npm -i -D carbon-components-svelte
 ```
 
 ## Usage
 
+The quickest way to get started is to customize a template from the [examples](examples/) folder.
+
+Example set-ups demonstrate usage with popular application bundlers and frameworks. They feature a mix of Singe-page Applications (SPA), Server-side rendering (SSR) and statically exported approaches.
+
+- **[rollup](examples/rollup/)**: SPA bundled using [Rollup](https://github.com/rollup/rollup)
+- **[rollup-typescript](examples/rollup-typescript/)**: SPA bundled using [Rollup](https://github.com/rollup/rollup) with TypeScript support
+- **[routify](examples/routify/)**: SPA + static export using [Routify](https://github.com/roxiness/routify)
+- **[sapper](examples/sapper/)**: SSR + static export using [Sapper](https://github.com/sveltejs/sapper)
+- **[svite](examples/svite/)**: SPA developed with Svite, bundled with [Rollup](https://github.com/rollup/rollup)
+- **[webpack](examples/webpack/)**: SPA bundled with [webpack](https://github.com/webpack/webpack)
+
+### Scaffolding
+
+Each example is published in a dedicated branch of the same name.
+
+Use [degit](https://github.com/Rich-Harris/degit) to scaffold a new project:
+
+For example, to use the `svite` template, run the following commands:
+
+```sh
+npx degit ibm/carbon-components-svelte#svite svelte-app
+cd svelte-app
+yarn install
+```
+
+### Importing components
+
+Import components from `carbon-components-svelte` in the `script` tag of your Svelte file.
+
 ```html
+<!-- App.svelte -->
 <script>
-  import { Button } from "carbon-components-svelte";
+  import { Accordion, AccordionItem } from "carbon-components-svelte";
 </script>
 
-<svelte:head>
+<Accordion>
-  <link
+  <AccordionItem title="Section 1" open> Content 1 </AccordionItem>
-    rel="stylesheet"
+  <AccordionItem title="Section 2"> Content 2 </AccordionItem>
-    href="https://unpkg.com/carbon-components/css/carbon-components.min.css"
+  <AccordionItem title="Section 3"> Content 3 </AccordionItem>
-  />
+</Accordion>
-</svelte:head>
-
-<Button>Primary</Button>
 ```
 
+**Refer to [COMPONENT_INDEX.md](COMPONENT_INDEX.md) for component API documentation.**
+
+### Precompiled CSS StyleSheets
+
+`carbon-components-svelte` includes precompiled CSS StyleSheets for each Carbon theme:
+
+- **white.css**: Default Carbon theme (light)
+- **g10.css**: Gray 10 theme (light)
+- **g90.css**: Gray 90 theme (dark)
+- **g100.css**: Gray 100 theme (dark)
+- **all.css**: All themes (White, Gray 10, Gray 90, Gray 100) using CSS variables
+
+Each StyleSheet is [generated](scripts/build-css.js) from the flagship [carbon-components](https://github.com/carbon-design-system/carbon/tree/master/packages/components) library.
+
+The [examples](examples/) use `all.css` for dynamic theming through CSS variables.
+
+Because the CSS is precompiled, it includes all Carbon design styles. One method to optimize the CSS is to ship only the CSS that is used. This can be accomplished using [PurgeCSS](https://github.com/FullHuman/purgecss) with a Carbon style extractor (WIP).
+
+#### Usage
+
+##### `svelte-preprocess`
+
+The easiest way to import a StyleSheet is with [svelte-preprocess](https://github.com/sveltejs/svelte-preprocess).
+
+```js
+const svelteOptions = {
+  preprocess: require("svelte-preprocess")(),
+};
+```
+
+```html
+<!-- App.svelte -->
+<style global>
+  /** Gray 10 theme **/
+  @import "carbon-components-svelte/css/g10";
+</style>
+```
+
+##### JavaScript import
+
+Importing a CSS file in a JavaScript file will require the appropriate file loader(s).
+
+```js
+import "carbon-components-svelte/css/all.css";
+import App from "./App.svelte";
+
+const app = new App({ target: document.body });
+
+export default app;
+```
+
+See [webpack.config.js](examples/webpack/webpack.config.js) in [examples/webpack](examples/webpack).
+
 ### TypeScript support
 
-This library ships with TypeScript definitions ([types/index.d.ts](types/index.d.ts)).

+
+## Getting started
+
+Scaffold a new project using [degit](https://github.com/Rich-Harris/degit):
+
+```sh
+npx degit ibm/carbon-components-svelte#sapper svelte-app
+cd svelte-app
+yarn install
+```
+
+## Available scripts
+
+### `yarn dev`
+
+Runs the app in development mode.
+
+### `yarn build`
+
+Builds the app for production (SSR).
+
+### `yarn export`
+
+Builds the app for production and statically exports the app.
+
+### `yarn start`
+
+Runs the app in production (`yarn build` must be run first).
