 Make sure the passed title matches the article title, and the tool should be able to find the wikidata entry.
 The next section will go over what these infobox templates files are, where you can find them on wikipedia, and how you can customize them locally for your wikidata analysis.
 
+### Interpretation of output
+The left column of the table first lists all the properties that the infobox requires.
+The right column will display the same property name if it is present in wikidata.
+If it is not present, the right column will be blank.
+Remaining properties in wikidata that are not required by the infobox are trailed in the right column.

 ## Templates

 The goal of this tool is to be universal, but these templates have not been standardized as far as I am aware.
