+String: A UTF‐8 character sequence.

+## The process for adding a new field:
+
+1. First we need to add the field to our type in datamodel.graphql
+2. Then, we need to add it to our schema.graphql file, which is how we define our GraphQL API. Here we will only include the fields that we want to be query-able
+3. Now the database needs to know about the new field, so we run `prisma deploy`
