 ## 🎨 Styling
 
-Default styles are loaded automatically when you use the plugin. You can also modify the styles since the plugin uses a modular class structure that makes it easy to customize the appearance:
+By default, styles are automatically injected into your document. You can customize this behavior:
+
+### Automatic Style Injection (Default)
+
+Styles are included automatically when you use the plugin with default settings:
+
+```typescript
+unified().use(remarkNotes) // Styles auto-injected
+```
+
+### Manual Style Import
+
+If you prefer to manage styles yourself (e.g., for SSR or custom build tools), disable auto-injection:
+
+```typescript
+unified().use(remarkNotes, { injectStyles: false })
+```
+
+Then manually import the CSS:
+
+```typescript
+import 'remark-notes-plugin/styles.css'
+```
+
+### Customizing Styles
+
+The plugin uses a modular class structure that makes it easy to customize the appearance:
 
-### Base Classes
+#### Base Classes
 
 - `.remark-note` - Base container for all note types
 - `.remark-note-header` - Note header container
 - `.remark-note-icon` - Icon styling
 - `.remark-note-title` - Note title styling
 - `.remark-note-content` - Note content container
 
-### Type-Specific Classes
+#### Type-Specific Classes
+
+- `.remark-note-note` - Note type styling
+- `.remark-note-tip` - Tip type styling
+- `.remark-note-important` - Important type styling
+- `.remark-note-quote` - Quote type styling
+- `.remark-note-bonus` - Bonus type styling
+
+#### Custom Class Prefix
+
+You can add a custom prefix to all CSS classes:
+
+```typescript
+unified().use(remarkNotes, { classPrefix: 'my-callout' })
+```
+
+This generates classes like:
 
-- `.remark-note.note` - Note type styling
-- `.remark-note.tip` - Tip type styling
-- `.remark-note.important` - Important type styling
-- `.remark-note.quote` - Quote type styling
-- `.remark-note.bonus` - Bonus type styling
+- `.my-callout-remark-note`
+- `.my-callout-remark-note-tip`
+- `.my-callout-remark-note-header`
+- etc.

 }
