Usage
Each cell in the first ("Markup") column uses to retain newlines and spaces but styled to allow content to wrap within it. It is usually desirable to escape the content of these cells so that the markup is displayed by wrapping the markup in nowiki. It is technically not possible to add this feature to the template.

Each cell in the second ("Renders as") column is usually the unescaped markup copied from the corresponding "Markup" cell before it. There are instances where this may differ:
 * If the first line includes wikimarkup that must start on a new line such as #, * or ; then use  before the first line; see examples below.
 * Header markup such as == will show in the page table of contents; use.
 * Some templates will place the page in a maintenance category, which is usually undesired:
 * Instead of, use.
 * Some templates may have error checking that places the page in a maintenance category. Suppress the category as possible:
 * templates can suppress the maintenance category by setting true.

nowiki
If you don't wrap the content of the markup cell in nowiki, then any template markup will not be escaped, it will be expanded.

This example shows the markup for tag :

HTML entities
HTML entities are parsed in the markup cell:

To work around this, replace the  with   thus   will show as

List and indent markup
If the first line includes wikimarkup that must start on a new line such as #, * or ; then use :

More complex
Note that Markup's second argument here uses fake heading and fake citation needed.

Showing rendered HTML
When a template is enclosed within code, it shows the rendered HTML:
