+# Badge
+
+The badge lets you add status to your headers. For example, it could be useful to specify the section's type, or supported version.
+
+## Usage
+
+You may use the `Badge` component which is globally available.
+
+```html
+### Title <Badge type="info" text="default" />
+### Title <Badge type="tip" text="^1.9.0" />
+### Title <Badge type="warning" text="beta" />
+### Title <Badge type="danger" text="caution" />
+```
+
+Code above renders like:
+
+### Title <Badge type="info" text="default" vertical="middle" />
+### Title <Badge type="tip" text="^1.9.0" vertical="middle" />
+### Title <Badge type="warning" text="beta" vertical="middle" />
+### Title <Badge type="danger" text="caution" vertical="middle" />
+
+## Custom Children
+
+`<Badge>` accept `children`, which will be displayed in the badge.
+
+```html
+### Title <Badge type="info">custom element</Badge>
+```
+
+### Title <Badge type="info">custom element</Badge>
+

+  --vp-badge-info-bg: var(--vp-c-white-soft);
+
+  --vp-badge-tip-border: var(--vp-c-green-dimm-1);

+  --vp-badge-danger-text: var(--vp-c-red-light);
+}
+```

+## `<Badge>`
+
+`<Badge>` component accepts following props:
+
+```ts
+interface Props {
+  // When `<slot>` is passed, this value gets ignored.
+  text?: string
+
+  // Defaults to `tip`.
+  type?: 'info' | 'tip' | 'warning' | 'danger'
+}
+```
