Adding a new article to existing publication(That subscribers have not been generated based on snapshot) in SQL SERVER 2008 R2

Hi Everyone,

I want to add a new article to existing publication in a transactional replication in sql server 2008 R2. The subscribers have not been generated based on snapshot. Now if I try to add new article, do I need to run snapshot agent or just I need to add the new article manually in subscriber and refill it and then add it to publication?

Regards,

AG
