How to allow a Contributor/Author to post to a Page listed on my main menu

Hello, what is the best way to allow a client to update content posts like blog posts so that for example I could put a “News” menu link on my sites main menu and on viewing that all the content is what the client has posted?

So lets say I setup a Category “News” then I make the clients account either Author or Contributor I’m not sure which would be best so they can create posts like news updates or press releases and they show up on the “page” listed on my menu?

Hope thats clear enough. Thanks.
