 + **CSS:** Apply custom CSS styling to the image captions.<br/>
 Captions are indexed from 1 using the 'data-image-caption-index' attribute for styling based on figure number.
 
++ **Delimeter:** Indicates the caption text.<br/>
+A delimeter is a set of characters that identify the caption text to use.
+ + If blank, the entire text is used.
+ + A single delimeter can be used.<br/>
+    e.g. `"` -> `"My caption"` or `!!` -> `!!My caption!!`
+ + A start and end delimter can be used by separating them with a comma (,).<br/>
+    e.g. `{, }` -> `{My caption}` or `<<, >>` -> `<<My caption>>`
+ + **Note:** Whitespace is trimmed from the delimeter character sets.
+ + **Note:** Only the first and last delimeters are matched, so the delimeter character can be used in the caption without special consideration, such as escaping.
+
 ## FAQ
 
 + **My captions aren't showing up:** Captions are only added if the image is rerendered. Try changing the caption (needs to be more than a trialing space) and trying again. If this fixes the issue then change it back, otherwise open an Issue.
