+Any images should be included.
+Do not return the Markdown as a code block, only as a raw string, without any new lines.
+
+No data or information should ever be removed, it should only be processed and formatted.
+
+There are in-text citations/references in the text, remove them from the text (**but most importantly, keep the reference number in the text. use a <sup></sup> tag**) and put them into an object where the key is the reference number and the value is the text. If any citations contain JSON-breaking characters, ensure they are properly escaped. This includes characters like double quotes, backslashes, and newlines.
+
+The Markdown should be human-readable and well-formatted. The markdown string should properly sanitized and should not break a JSON parser when returned as the final format.
