Some "downloading" that should be "uploading".
Some bullet points with "code" items were rendering with bold, italics on the published page. These seemed to be bullet points that had 3 spaces at the start of their 2nd line of text. Other bullet points that rendered correctly had only 2 spaces. So I removed the extra space. I hope it renders nicely in the published form - it is a bit hard to know in the GitHub Preview, because that is trying to show change-sidebars and differences also.
