Two default themes are included in the core package, `light.css` and `dark.css`, and others can be found on the Speed Highlight [GitHub](https://github.com/speed-highlight/core/tree/main/src/themes), but you can also easily create your own.
+When using dark mode, there are two different themes that have to be changed: the editor theme and the one used for syntax highlighting:
+
+<Code>
+
+```css
+/* Editor dark mode */
+/* Only if you are using the default theme */
+html.dark .carta-theme__default {
+	--border-color: var(--border-color-dark);

+## Changing Markdown input color theme
+
+Carta uses [Shiki](https://shiki.matsu.io/) for syntax highlighting. Two default themes are included in the core package, which are set as a [dual theme](https://shiki.matsu.io/guide/dual-themes) to support light and dark mode. If you plan to use a custom one with light/dark modes, make sure to use a dual theme as well.
+
+You can change theme in the options:
+
+<Code>
+
+```ts
+const carta = new Carta({
+	// ...
+	theme: 'github-dark'
+});
+```
+
+</Code>
+
+If you use a [custom theme](https://shiki.matsu.io/guide/load-theme)(or a custom language), you need to provide it inside the options, so that it gets loaded into the highlighter:

+
+# Major Changes
+
+## Removal of Marked
+
+Marked has been replaced with a combination of Unified, Remark and Rehype. If you previously used a custom plugin with it, you'll have to update it manually. Otherwise, all builtin plugins have already been updated. Make sure to **update** them!
+
+Some plugins now have a different implementation and their options have changed. Those plugins are [plugin-math](https://beartocode.github.io/carta/plugins/math) and [plugin-anchor](https://beartocode.github.io/carta/plugins/anchor).
+
+## Syntax highlighter update
+
+SpeedHighlight has been replaced with [Shiki](https://shiki.matsu.io/). It now offers support for more languages, themes, and extensibility.
+
+Make sure to remove previous themes imports, as Shiki uses JS based ones.
+
+```ts
+import 'carta-md/light.css'; // 👈 To be removed!
+```
+
+And also update the default theme. Previous based selectors should be removed:
+
+```css
+/* 👇 To be removed! */
+[class*='shj-lang-'] {
+	/* ... */
+}
+```
+
+## Removed verbose prefixes
+
+Many exports have been renamed to make them less verbose:
+
+- `CartaEditor` -> `MarkdownEditor` (old one still supported);
+- `CartaRenderer` -> `Markdown` (old one still supported);
+- `CartaEvent` -> `Event`;
+- `CartaEventType` -> `EventType`;
+- `CartaExtension` -> `Plugin`;
+- `CartaExtensionComponent` -> `ExtensionComponent`;
+- `CartaOptions` -> `Options`;
+- `CartaHistory` -> `TextAreaHistory`;
+- `CartaHistoryOptions` -> `TextAreaHistoryOptions`;
+- `CartaIcon` -> `Icon`;
+- `CartaListener` -> `Listener`;
+- `CartaInput` -> `InputEnhancer`;
+- `CartaRenderer` -> `Renderer`;
+- `CartaLabels` -> `Labels`;
+
+# Minor Changes
+
+- If you don't use a sanitizer, you need to explicitly set it to `false`;
+- Removed deprecated option `cartaRef` and `shjRef` for extensions;
+- Removed deprecated options `postProcess` for `plugin-tikz`;
+- `Carta.options` are no longer available.

+
+Svelte components can be embedded into the rendered HTML to make certain elements interactive. However, they require a bit more work, as Remark is configured to only render static HTML. To get around this, the idea is to do the following:
+
+1. Create a Unified plugin to isolate the targeted element;
+2. Replace all the elements with the component, after every render.
+
+## Example
+
+Let's say we want to replace all hashtags, such as `#something`, with a custom component. Here is as example of how that could be achieved.
+
+### Parsing the hashtags
+
+First things first: we need to tell the parser that we want to parse hashtags as custom elements. To do this, it's useful to first install the following packages:
+
+<Code>
+
+```shell
+npm i unist-util-visit
+# Types
+npm i -D unified hast
+```
+
+</Code>
+
+Let's create a Unified plugin. The basic structure of a plugin is the following:
+
+<Code>
+
+```ts
+import type { Plugin as UnifiedPlugin } from 'unified'
+import { SKIP, visit } from 'unist-util-visit'
+
+const unifiedPlugin: UnifiedPlugin<[], hast.Root> = () => {
+	return function (tree) {
+    // Visit every node in the syntax tree
+    visit(tree, (node, index, parent) => {
+      // Do something with the node
+    }
+  }
+}
+```
+
+</Code>
+
+We now want to parse text nodes, so that words such as `#pizza` and `#123` are separated from the rest. This is a possible implementation:
+
+<Code>
+
+```ts
+const unifiedPlugin: UnifiedPlugin<[], hast.Root> = () => {
+	return function (tree) {
+		visit(tree, (node, index, parent) => {
+			// Skip code blocks and their children
+			if (node.type === 'element' && node.tagName === 'pre') return [SKIP];
+			// Skip non-text nodes
+			if (node.type !== 'text') return;
+			const text = node as hast.Text;
+
+			// Parse the text node and replace hashtags with spans
+			const regex = /#(\w+)/g;
+			const children: (hast.Element | hast.Text)[] = [];
+			let lastIndex = 0;
+			let match;
+			while ((match = regex.exec(text.value))) {
+				const before = text.value.slice(lastIndex, match.index);
+				if (before) {
+					children.push({ type: 'text', value: before });
+				}
+				children.push({
+					type: 'element',
+					tagName: 'span',
+					properties: { type: 'hashtag', value: match[1] },
+					children: [{ type: 'text', value: match[0] }]
+				});
+				lastIndex = regex.lastIndex;
+			}
+			if (lastIndex < text.value.length) {
+				children.push({ type: 'text', value: text.value.slice(lastIndex) });
+			}
+
+			// Replace the text node with all the children
+			parent!.children.splice(index!, 1, ...children);
+
+			// Skip the children
+			return [SKIP, index! + children.length];
+		});
+	};
+};
+```
+
+</Code>
+
+If you want a more in-depth guide on writing Unified plugins, you can check out the official [documentation](https://unifiedjs.com/learn/guide/create-a-plugin/).
+
+Notice that hashtags are now replaced with the following:
+
+```html
+<span type="hashtag" value="pizza"> #pizza </span>
+```
+
+### Configuring the transformer
+
+Unified plugins need to be wrapped inside a `UnifiedTransformer` type, to be able to be used in Carta.
+
+<Code>
+
+```ts
+import type { UnifiedTransformer } from 'carta-md';
+
+const hashtagTransformer: UnifiedTransformer<'sync'> = {
+	execution: 'sync', // Sync, since the plugin is synchronous
+	type: 'rehype', // Rehype, since it operates on HTML
+	transform({ processor }) {
+		processor.use(unifiedPlugin);
+	}
+};
+```
+
+</Code>
+
+### Mounting the components
+
+We now want to replace the generated hashtag placeholders with the following element:
+
+<Code>
+
+```svelte
+<!-- Hashtag.svelte -->
+<script>
+	export let value;
+</script>
+
+<button
+	on:click={() => {
+		console.log('Hashtag clicked!');
+	}}
+>
+	#{value}
+</button>
+```
+
+</Code>
+
+To do that, we create a listener that:
+
+1. Finds all the previous placeholders;
+2. Mounts the component next to them;
+3. Removes the placeholders.
+
+<Code>
+
+```ts
+import type { Listener } from 'carta-md';
+import Hashtag from './Hashtag.svelte';
+
+const convertHashtags: Listener<'carta-render'> = [
+	'carta-render',
+	function onRender({ detail: { carta } }) {
+		const rendererContainer = carta.renderer?.container;
+		if (!rendererContainer) return;
+
+		// Find all hashtag spans and replace them with Svelte components
+		const hashtagSpans = rendererContainer.querySelectorAll('span[type="hashtag"]');
+		for (const span of hashtagSpans) {
+			const hashtag = span.getAttribute('value') ?? '';
+
+			new Hashtag({
+				target: span.parentElement!,
+				anchor: span,
+				props: { value: hashtag }
+			});
+
+			span.remove();
+		}
+	}
+];
+```
+
+</Code>
+
+### Using the plugin
+
+Let's now create a Plugin with the transformer and the listener:
+
+<Code>
+
+```ts
+import type { Plugin } from 'carta-md';
+
+export const hashtag = (): Plugin => ({
+	transformers: [hashtagTransformer],
+	listeners: [convertHashtags]
+});
+```
+
+</Code>
+
+We can now use the plugin with the following:
+
+```ts
+import { Carta } from 'carta-md';
+
+const carta = new Carta({
+	// ...
+	extensions: [hashtag()]
+});
+```
+
+You can find the example source code [here](https://github.com/BearToCode/svelte-in-carta-example).

 ### Using the default highlighter
 
-Carta comes with a default highlighter that matches the one used to highlight markdown in the editor and is used by default.
-The theme is the same as the one used in the main carta package (`carta-md/light.css` or `carta-md/dark.css`).

+Carta comes with a default highlighter that matches the one used to highlight markdown in the editor and is used by default (Shiki). If you want to use a theme different from the one used to highlight Markdown, you can specify it in the options. Remember to also have it loaded into the highlighter, by specifying it in `shikiOptions`.
 
 ```ts
-code({
-	customHighlight: {
-		highlighter: (code, lang) => myCustomHighlighter(code, lang),
-		langPrefix: 'my-highlighter-'

+### Using a custom highlighter
+
+It is no longer possible to specify a custom highlighter in this plugin. However, there are many different [Remark plugins](https://github.com/remarkjs/remark/blob/main/doc/plugins.md#list-of-plugins) that provide syntax highlighting.
