+- `emit` is responsible for looking at all the parsed and filtered content and then appropriately creating files and returning a list of paths to files the plugin created.
+- `partialEmit` is an optional function that enables incremental builds. It receives information about which files have changed (`changeEvents`) and can selectively rebuild only the necessary files. This is useful for optimizing build times in development mode. If `partialEmit` is undefined, it will default to the `emit` function.
+- `getQuartzComponents` declares which Quartz components the emitter uses to construct its pages.
 
 Creating new files can be done via regular Node [fs module](https://nodejs.org/api/fs.html) (i.e. `fs.cp` or `fs.writeFile`) or via the `write` function in `quartz/plugins/emitters/helpers.ts` if you are creating files that contain text. `write` has the following signature:

+title: Reader Mode
+tags:
+  - component
+---
+
+Reader Mode is a feature that allows users to focus on the content by hiding the sidebars and other UI elements. When enabled, it provides a clean, distraction-free reading experience.
+
+## Configuration
+
+Reader Mode is enabled by default. To disable it, you can remove the component from your layout configuration in `quartz.layout.ts`:
+
+```ts
+// Remove or comment out this line
+Component.ReaderMode(),
+```
+
+## Usage
+
+The Reader Mode toggle appears as a button with a book icon. When clicked:
+
+- Sidebars are hidden
+- Hovering over the content area reveals the sidebars temporarily
+
+Unlike Dark Mode, Reader Mode state is not persisted between page reloads but is maintained during SPA navigation within the site.
+
+## Customization
+
+You can customize the appearance of Reader Mode through CSS variables and styles. The component uses the following classes:
+
+- `.readermode`: The toggle button
+- `.readerIcon`: The book icon
+- `[reader-mode="on"]`: Applied to the root element when Reader Mode is active
+
+Example customization in your custom CSS:
+
+```scss
+.readermode {
+  // Customize the button
+  svg {
+    stroke: var(--custom-color);
+  }
+}
+```

+## `ConditionalRender` Component
+
+The `ConditionalRender` component is a wrapper that conditionally renders its child component based on a provided condition function. This is useful for creating dynamic layouts where components should only appear under certain conditions.
+
+```typescript
+type ConditionalRenderConfig = {
+  component: QuartzComponent
+  condition: (props: QuartzComponentProps) => boolean
+}
+```
+
+### Example Usage
+
+```typescript
+Component.ConditionalRender({
+  component: Component.Search(),
+  condition: (props) => props.displayClass !== "fullpage",
+})
+```
+
+The example above would only render the Search component when the page is not in fullpage mode.
+
+```typescript
+Component.ConditionalRender({
+  component: Component.Breadcrumbs(),
+  condition: (page) => page.fileData.slug !== "index",
+})
+```
+
+The example above would hide breadcrumbs on the root `index.md` page.
