What two steps must an admin take to configure Live Stop Associations?

According to the Salesforce Help article on Configuring Stop Associations for Live Daily SummaryConfigurations in Salesforce Maps3, two steps that an admin must take to configure Live Stop Associations are: create a Marker Layer that includes all records users will visit, and create a Shape Layer for each record that specifies the radius for associating a Stop event3. The Marker Layer will help identify the records that are relevant for Stop Associations, and the Shape Layer will help define the distance around each Stop Event that will be used to determine which records will associate with the Stop Event3.
