I know this issue has come up several times in the past, but all of the old posts have not been helpful (and some are really out of date and should be deleted). When I select "Embed on a web page" from the "Share" menu it shows two steps: 1) paste a script tag in the head section of the webpage, and 2) paste a div in an HTML block. Step 2 seems straightforward enough (or is it?), but how do you put the script in the head section of a Wordpress page or post? Why isn't there a plugin for this? Thanks.
