I follow the tutorial on the RStudio site and add toc: true in the yaml options. However, the previewed document doesn't have a table of content.
Here is my yaml options.

output:
github_document:
df_print: tibble
toc: true
toc_depth: 2
bibliography: add.bib

The .Rmd document is posted on the Github.
And the .md document is knited and posted here.
Anyone do sort of things on the Github before?
