Templates for chunk categorisation
From Joomla! Documentation
On this page you will find several Wiki Templates to help you categorise modular content items according to the information provided in the article "Categorising a chunk".
Templates[edit]
Wiki templates are wiki pages which can be used in other pages using a technique called transclusion. They reside in their own content namespace to avoid name clashing with regular articles. In order to use such a template, all you have to do is to enclose its name in curly brackets: {{template name}}.
Chunks[edit]
A chunk is a small, focussed, stand-alone piece of content that is written so that it makes sense even when taken out of context. Each chunk can be thought of as answering a basic question (who?, what?, where?, when?, why?, how?) and we categorise the chunks according to the type of answer we are giving (for example, a topic, procedure, definition, figure or table).
