NOTES: If changing the title (to match the new Google font), simply replace it in the “title” section and list it in the “google fonts” section. - If it doesn't work, you may need to shift how it's listed in "google fonts" (at the top, in the middle, etc). Just make sure that there is a comma after all of them EXCEPT the last one listed :)
P.S. You can do this with the other fonts too, just follow the same instructions.
