Blogging with 7.1

I am trying to understand how collection pages work, especially with blogging. None of the videos or tutorials explain where the blog overview page shows up and how to use it. Very confused here!

@Shares When you add a blog, you'll see this in your side bar (Website > Pages):

If you click on it, it will open up into this menu:

The Blog Overview page is the collection page for your blogs. You can modify the layout by clicking 'Edit' in the top left corner, then hovering over the page and clicking 'Edit Section' in the floating menu box. Here you can pick the layout, size of the blog title cards, what information is displayed, etc. 

You can also add sections to this page if there's other content you want included, such as a title.

Let me know if you have any additional questions!
