Blog pagination with multiple blogs (single site)

So I’m looking at the documentation surrounding pagination on blogs and I’m still left with questions.

  1. It’s mentioned to put this in the config file for pagination configuration: paginate_path: "/blog/page:num/" — but what do you do when you have more than one blog?

and the other item is this:

  1. It also mentions: " include the jekyll-paginate plugin in your Gemfile", which mine now reads this:
group :jekyll_plugins do
  gem "jekyll-feed", "jekyll-paginate", "~> 0.6"

I did both of these items and the pagination isn’t working at all and no sense if I’m in the right direction or not.
