 Linking in this style ensures that the links work when browsing the
 documentation on GitHub. If your Markdown editor makes links clickable, they
 will work there as well. When the documentation is built, these links will be
 converted into regular links which point to the built HTML pages.
 
+When linking to the objects in the [API documentation], simply use a reference
+to the dot path of the Python object. There is no need to define the
+reference as it is already predefined in a collection of global link
+references.

+```
+
+Note that as the link label contains code, it should be wrapped in a code span
+and the reference needs to be defined immediately after. This also allows a
+long dot path to be truncated for simplicity in the text.

 #### Notes and Warnings
 
 If you want to draw attention to a note or warning, use the syntax defined in
 Python-Markdown's [Admonition Extension]:
 
-```md
+``` markdown
 !!! note
 
     This is the content of the note.
 ```
 
+In addition to the [supported types] listed in Zensical's documentation, the
+`seealso` type is supported.
+
+``` markdown
+!!! seealso "See Also"
+
+    This should link to some relevant content contained elsewhere.
+```
+
+Unlike the other defined types, `seealso` needs the title to be manually
+defined as the default behavior will not split a generated title into two
+words.
+
+!!! seealso "See Also"
+
+    See Zensical's documentation on [supported types] for more information.
+
+#### Code Blocks
+
+All code blocks should use the fenced code block style. If a code block is
+demonstrating Markdown syntax, if can be assigned the `md-render` attribute,
+and both the Markdown source and HTML output will be rendered in a nested set
+of code blocks.
+
+```` markdown
+``` md-render
+Some *Markdown* text.
+```
+````
+
+The above code block will be rendered at follows:
+
+``` md-render
+Some *Markdown* text.
+```
+
+The rendered output is generated by an isolated Markdown instance, which is
+separate from the body text of the document. Extensions and configuration
+options are not carried over. If extension(s) need to be enabled for the code
+block, then they can be defined as YAML front-matter within the code block.
+The `extensions` and `extension_configs` keywords are the only options which
+are passed on to the isolated Markdown instance.The YAML front-matter is
+stripped from the body of the code block before the code block is passing to
+the isolated Markdown instance.
+
+```` markdown
+``` md-render
+---
+extensions: [toc]
+extension_configs:
+    toc:
+        permalinks: true
+---
+# A Markdown header
+```
+````
+
+The above code block would be rendered with the `toc` extension and that
+extension's `permalinks` option enabled as follows:
+
+``` md-render
+---
+extensions: [toc]
+extension_configs:
+    toc:
+        permalink: true
+---
+# A Markdown header
+```
+
+Note that the YAML front-matter must be deliminated by a line of at least three
+hyphens (both before and after) and be valid YAML. Any invalid formatting or
+unknown keywords will cause the entire block to not be recognized as a code
+block. Therefore, be sure to confirm the formatting before submitting
+proposed changes which utilize rendered code blocks.
+
+If a Markdown code block should not receive the special rendering described
+above, then simply assign it the `markdown` attribute. It will then be
+rendered as a normal Markdown code block.
+
+```` markdown
+``` markdown
+Some *Markdown* text.
+```
+````
+
+The above code block would render as follows:
+
+``` markdown
+Some *Markdown* text.
