+
+  Xpert Unit Summaries will summarize Text and Video Transcript text
+  for learners at the end of a unit to reinforce the information that
+  was contained in the unit.
+
+  When enabled by the course team, learners only need to click the
+  **Summarize button** at the bottom of the unit to see a condensed
+  summary of the content.
+
+  .. image:: ../../images/summary_button.png
+
+  .. image:: ../../images/summary_content.png
+
+  Learners can learn more about how the summary was generated by
+  clicking the **information icon below the summary.**
+
+  Learners can leave feedback about the summary using the **thumbs up
+  and down** icons at the bottom right of the summary card. This
+  feedback is only shared with edX for the purpose of improving the
+  tool.
+
+  .. note:: Not all pages have the Summarize button, as the system automatically selects which units are eligible for summarization based on the amount of text in the unit.
