References (or refs), on Wikipedia, are important to validate writing and inform the reader of the source of the text. When adding something to an article, it is highly advisable to cite a reference which describes the source of the information to help the reader who wishes to verify it, or to pursue it in greater depth. It is also useful to update or improve existing references.
