https://llllllllll.github.io/slider/appendix.html#collection should show up but it just shows the heading for me. Locally the docs show up as normal. @llllllllll can you make sure https://github.com/llllllllll/slider/blob/gh-pages/docs/source/appendix.rst reflects master branch? (I assume gh-pages is what is used for https://llllllllll.github.io/slider/)
