+/**
+ * Gravity Connect // Airtable // Create Phone Number Relation
+ *
+ * This snippet demonstrates how to create a relation between two tables in Airtable
+ * when a GC Airtable feed is being processed. It uses an example assuming the following:
+ *
+ * 1. There are a "People" table and "Phone Numbers" table in Airtable.
+ * 2. The "Phone Numbers" table has, at minimum, a phone number field and a link field.
+ * 3. There is a GCA feed that creates a record in the "People" table.
+ * 4. The snippet adds a phone number to the "Phone Numbers" table and creates a relation
+ *    between the newly created "People" record and the "Phone Numbers" record.
+ *
+ * Installation:
+ *   1. Install per https://gravitywiz.com/documentation/how-do-i-install-a-snippet/
+ *
