    ========================================
    #{class_name}Syncer has been generated!
    ========================================

    Files created:
    - app/syncers/#{file_name}_syncer.rb
    - db/migrate/..._add_filemaker_id_to_#{table_name}.rb
    - lib/tasks/sync_data.rake (updated with sync_#{file_name} task)

    Next steps:
    1. Run migrations: rails db:migrate

    2. Implement the records_to_create method
       - Set @total_create_required to the total number of records that should be created
       - Return an array of Trophonius records to create

    3. Implement the records_to_update method
       - Set @total_update_required to the total number of records that should be updated
       - Return an array of Trophonius records to update

    4. Implement the records_to_delete method (optional)
       - Return an array of record identifiers to delete

    Note: The total_required count used for sync tracking is automatically calculated
    from @total_create_required + @total_update_required

    5. Run the sync task:
       - Individual sync: rake sync:sync_#{file_name}
       - All syncs: rake sync:all
