+## Advanced Features
+
+### Slots
+
+You can use the `@slot` attribute with a few special values to insert
+content in various places :—
+
+- `@slot="shrine-head"` will place the content into the `<head>` of
+ the resulting document. This is especially useful for `<title>`,
+ `<meta>`, and `<style>` elements.
+
+- For `shrine-header` and `shrine-footer`, there are `-before` and
+ `-after` slot names which will place content into the beginning or
+ ending of the shrine header or footer, respectively.
+
+- You can define your own slots with `<slot>` in templates, headers,
+ and footers; this will enable a corresponding `@slot` name beginning
+ with `shrine-template-slot-`, `shrine-header-slot-` or
+ `shrine-footer-slot`, respectively.
+
+### Microdata
+
+You can use the H·T·M·L `@itemprop` attribute to define metadata for
+your site pages. The following values are supported :—
+
+- `shrine-title`: The title of the page.
+
+- `shrine-id`: A persistent, globally‐unique identifier for the page.
+
+- `shrine-updated`: The datetime that the page was last updated.
+
+Multiple values for a single `@itemprop` are not currently supported.
+Where possible, X·M·L markup will be preserved when accessing metadata
+values.
