 #. "categorical" if none of the above are satisfied.
 
+To use these catgeories the data should be in the format:
+- "boolean" - values should all be within ``["false", "true", "1.0", "0.0", "1", "0", "yes", "no"]``; coloring will be binary
+- "continuous" - values should be numeric; coloring will be a range between the minimum & maximum values
+- "temporal" - values should be dates in decimal date format (`2022.365`); coloring will be a range, and the legend will display human-readable dates
+- "ordinal" - values should be integers; coloring will be a range but all displayed values will be integers
+- "categorical" - each unique value will receive a different color, the color wheel will be repeated if necessary

 The provided colorings in the auspice-config JSON will result in corresponding
 metadata being exported. As mentioned above, for node-data provided metadata
