Help:Explanatory notes

Explanatory or content notes are used to add explanations, comments or other additional information relating to the main content but would make the text too long or awkward to read. Such notes may include supporting references.

Please read Help:Footnotes and Help:Shortened footnotes first, as this guide builds upon the methods described on those help pages. WP:REFGROUP is of particular importance.

This example uses list-defined references mixed with explanatory notes.
