+     "iheatmapr is an R package for building complex, interactive heatmaps
+using modular building blocks.  \"Complex\" heatmaps are heatmaps in which
+subplots along the rows or columns of the main heatmap add more information
+about each row or column.  For example, a one column additional heatmap may
+indicate what group a particular row or column belongs to.  Complex heatmaps
+may also include multiple side by side heatmaps which show different types of
+data for the same conditions.  Interactivity can improve complex heatmaps by
+providing tooltips with information about each cell and enabling zooming into
+interesting features. iheatmapr uses the plotly library for interactivity.")
