 ### Shortcodes with markdown
 
-In Hugo `0.55` we changed how the `%` delimiter works. Shortcodes using the `%` as the outer-most delimiter will now be fully rendered when sent to the content renderer. They can be part of the generated table of contents, footnotes, etc.
+Shortcodes using the `%` as the outer-most delimiter will be fully rendered when sent to the content renderer. This means that the rendered output from a shortcode can be part of the page's table of contents, footnotes, etc.
 
-If you want the old behavior, you can put the following line in the start of your shortcode template:
-
-```go-html-template
-{{ $_hugo_config := `{ "version": 1 }` }}
-```

 There are one caveat with this, and this isn't new, but it's worth mentioning here: There are situations in Hugo where you may see a cached value, e.g. when using `partialCached` or in a shortcode.
 
+## The `.RenderShortcodes` method {#rendershortcodes}
+
+{{< new-in "0.117.0" >}} This renders all the shortcodes in the content, preserving the surrounding markup (e.g. Markdown) as is.
+
+The common use case this is to composing a page from multiple content files while preserving a global context for table of contents and foot notes.
+
+This method is most often used in shortcode templates. A simple example of shortcode template including content from another page would look like:
+
+```go-html-template
+{{ $p := site.GetPage (.Get 0) }}
+{{ $p.RenderShortcodes }}
+```
+
+In the above it's important to understand  and the difference between the two delimiters used when including a shortcode:
+
+* `{{</* myshortcode */>}}` tells Hugo that the rendered shortcode does not need further processing (e.g. it's HTML).
+* `{{%/* myshortcode */%}}` tells Hugo that the rendered shortcode needs further processing (e.g. it's Markdown).
+
+The latter is what you want to use for the include shortcode outlined above:
+
+```md
+## Mypage
+{{%/* include "mypage" */%}}
+``````
+
+
+Also see [Use Shortcodes](/content-management/shortcodes/#use-shortcodes).

 ## Page-level params
 
 Any other value defined in the front matter in a content file, including taxonomies, will be made available as part of the `.Params` variable.
