+
+! Introduction
+
+The ''codeblock'' widget renders text in `<pre>` and `<code>` blocks, causing it to be
+displayed monospace. A language may optionally be specified using the
+''language'' attribute, however syntax highlighting will only be used if the
+[[Highlight Plugin]] is installed.
+
+! Content and Attributes
+
+The content of the `<$codeblock>` widget is ignored.
+
+|!Attribute |!Description|
+|code|Contents of the block to render as code|
+|language|Programming language for syntax highlighting|
+
+! Examples
+
+Here is an example embedding the contents of a tiddler as a code block.
+
+<$macrocall $name='wikitext-example-without-html'
+src='<$codeblock code={{$:/editions/tw5.com/macro-examples/say-hi}} />' />
+
+A codeblock may also specify a language.
+
+<$macrocall $name='wikitext-example-without-html'
+src='<$codeblock code="SELECT * FROM users WHERE deleted = false" language="sql" />' />
