+        <p>
+            PLUTO is a remarkable dataset. Used by urban planners, developers,
+            researchers, and civic hackers, PLUTO is a digital palimpsest of
+            evolving visions for the city. It offers a rich view into 20+ years
+            of sociopolitical, economic, and regulatory history, as well as
+            chronicling the Department of City Planning’s (DCP) evolving data
+            collection methods.

+        <p>
+            The interface you are looking at presents one interpretation of
+            PLUTO. In the future, I hope to collect feedback and make the tool
+            more useful to others. If you have any ideas, please reach out to me
