{{Pre2/doc}} uses <pre> tags, but with text that is either wrapped or is contained in a horizontal scrollbox. This means the text will not stretch past the right side of the screen.

If you want to disable wikitext in it, you should use <nowiki> tags inside the template (see below).

{{Pre2|Text to be displayed. And more and more and more... and an empty line

And then more and more...}}
produces:
Text to be displayed. And more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and an empty line.

And then more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more.
{{Pre2|scroll|Text to be displayed. And more and more and more... and an empty line.

And then more and more...}}
produces:
Text to be displayed. And more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and an empty line.

And then more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more and more.

When the text contains links is better to change the text color, thus highlighting:

{{Pre2|style=color:green|Text to be a [[Hyperlink|link]]. WARNING! To include A{{=}}B inside of text, you must use Template:{{=}}. Like this: A{{((}}{{=}}{{)}}B.}}
produces:
Text to be a link. WARNING! To include A=B inside of text, you must use Template:=. Like this: A{{=}}B.

To disable wikitext (e.g. [[links]]), <nowiki>...</nowiki> tags must be used in the form:

{{Pre2|<nowiki>Your [[text]]{{dn|name=Pre2}}, which ''might'' include {{tl|templates}}.<noinclude>[[Category:Example]]</noinclude></nowiki>}}

This will produce this:

Your [[text]]{{dn|name=Pre2}}, which ''might'' include {{tl|templates}}.<noinclude>[[Category:Example]]</noinclude>

as opposed to (note, that <noinclude>...</noinclude> part is no present):

Your text[disambiguation needed], which might include {{templates}}.Category:Example
