| 18 | +// syntax explanation: |
| 19 | +// - the [[...]] creates an anchor at the list item |
| 20 | +// - The <<...>> creates a link to the achor |
| 21 | +// - The {li} references the pass that you can find at the top of the document, it is a FontAwesome icon |
| 22 | +// - The ...:: is the syntax for a definition list item |
| 23 | +// - The {empty} followed by the + means that there is no "normal" list item, instead there is a block |
| 24 | +// - The period followed by text is the summary of a details block that is collapsed |
| 25 | +// - Inside the "====" is the details of the details block. |
| 26 | +// |
| 27 | +// Please create new entries the same way! This allows easy linking to glossary items. |
| 28 | +// Antora generates dl, dt and dd tages for the definition list, which is great because these are |
| 29 | +// semantic HTML tags. |
