-This is a convenience method, useful within partial templates that are called from both [shortcodes] and page templates.
-
-{{< code file=layouts/shortcodes/foo.html  >}}
-{{ partial "my-partial.html" . }}
-{{< /code >}}
-
-When the shortcode calls the partial, it passes the current [context] (the dot). The context includes identifiers such as `Page`, `Params`, `Inner`, and `Name`.
-
-{{< code file=layouts/_default/single.html  >}}
-{{ partial "my-partial.html" . }}
-{{< /code >}}
-
-When the page template calls the partial, it also passes the current context (the dot). But in this case, the dot _is_ the `Page` object.
-
-{{< code file=layouts/partials/my-partial.html  >}}
-The page title is: {{ .Page.Title }}
-{{< /code >}}
-
-To handle both scenarios, the partial template must be able to access the `Page` object with `Page.Page`.
-
-{{% note %}}
-And yes, that means you can do `.Page.Page.Page.Page.Title` too.
-
-But don't.
-{{% /note %}}
