A definition is a common way to start an iQpedia article. Your first paragraph should give a brief, basic overview of the term. Many people will quickly skim this paragraph and decide to read on or search for something else.
Your second paragraph can go into greater detail. Here writers can go into secondary information.
If there is any historical information that may provide background, put that under the heading of "History." For instance, in the article about the TECUnit, it may be useful to know that the Teststing Evaluation and Certification Unit used to be called the "Training Evaluation and Certiciation Unit." At that time they offered classes, which they no longer do. It might also be interesting to know that the TECUnit began as a committee of the National Cued Speech Association. These historical perspectives can be intereting and useful but may not be essential information for everyone. It can be helpful to put them in their own headin so that people can skim the article quickly.
The whole purpose behind dailycues is to provide cuers with our own place to deposit information that is useful to our community. When writing an article, try to draw connections between the article's main topic and Cued Speech. How does the topic related to cuers? What might a transliterator need to know about this topic? Help the reader see the relevance of this article.
Sometimes it may be worth providing some information on signed languages. For instance, if you're editing the article "phoneme", you might want to add a section on how contrastic segments occur in those languages. It may be worth creating a whole section so that the reading can decide if they want to venture into applications to signed languages or stick to spoken languages.
Relevant external links can be placed in a deveoted section.
Terms that may be related, but not relevant for the body of the article can be listed below in a "See Also" section.
