 # How to Add / Update
 To add or update a person's entry, modify the JSON entry in `people.json`. People with spaces in their surname should use underscore e.g. Le_Blanc.
 It will be displayed properly with a space. The "interests" for each person need to come from Wikipedia main entries - that is our controlled vocabulary.
