== Usage ==&lt;br /&gt;
This template &amp;#039;&amp;#039;&amp;#039;&amp;lt;nowiki&amp;gt;{{WikiProject Engineering}}&amp;lt;/nowiki&amp;gt;&amp;#039;&amp;#039;&amp;#039; adds articles to subcategories of [[:Category:WikiProject Engineering articles]] and is a self-reference. Please add it to talk pages of relevant articles and non-article pages.&lt;br /&gt;
&lt;br /&gt;
This template should be [[Wikipedia:Transclusion|transcluded]] as {{tl|WikiProject Engineering}} and not substituted [[Wikipedia:Template substitution|{{subst:}}]] because it employs conditional code. Transclusion also allows easy updating of all the WikiProject&amp;#039;s talk pages without having to edit thousands of pages individually. For examples of how the template will appear under various parameter scenarios, please see {{oldid|Template:WikiProject Engineering/Examples|213771118|WikiProject Engineering/Examples}}.&lt;br /&gt;
&lt;br /&gt;
The template also employs several optional data field parameters as described below. The full syntax is as follows:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;div style=&amp;quot;width: 350px; background: #dddddd; border: 1px solid black; padding:0.5em 1em 0.5em 1em;&amp;quot;&amp;gt;&amp;lt;syntaxhighlight lang=&amp;quot;wikitext&amp;quot;&amp;gt;&lt;br /&gt;

=== Notes ===&lt;br /&gt;
To avoid needlessly cluttering up talk pages, it is usually appropriate to remove any unused parameters from the template. A common initial configuration for the template includes the following basic parameters:&lt;br /&gt;
{{center|1=&amp;lt;nowiki&amp;gt;{{WikiProject Engineering|class=|importance=|imageneeded=|imagedetails=|in=|unref=}}&amp;lt;/nowiki&amp;gt;}}&lt;br /&gt;
