                 <i>Note 1</i>: You can insert an image from your media library into the body of the article with an expression like this:

                 <i>Note 2</i>: You can use the <i>declare</i> function within the Twig code to change some template settings without having to change it for all the other articles. 
                 For example, <b>{{ declare('timeline-label', 'Events', a) }}</b> changes the label of the list of events displayed on the <i>Analysis</i> page, which now displays the text "Events" instead of "Timeline".
