Broken link, using sliders in Jolene

In another thread about how to use sliders, you referenced another link at https://wpblogs.ru/themes/blog/configure-sliders-for-your-website/ – but that link returned a 404. In fact, all of the links under “How to use a Theme” are broken.
It looks like there’s some really useful information there. Could you see if those links can be sorted out?
Thanks much!
