Blog tool

Are there better instructions someplace for the blog tool? It was just added to my course in the new template, and I can't find any instructions to help students create blogs. Can blogs be graded? Can a link to blogs be added to the Content Menu? Or to the ribbon at the top of the page? I can't even find a way to add a link to the blog page in an html document or assignment. This is the only info I can find, but it's not helpful: Any other suggestions?
