This is the project "Speaking: The Free Book Chapter" based on R Markdown and bookdown (https://github.com/rstudio/bookdown). (Please see the page "Get Started" at https://bookdown.org/yihui/bookdown/ for all docs this is based on.)
This project is version controlled via github.com/vitpia/speaking/. This project is accessible as a book via bookdown.org/v_piai_research/speaking/
You can find the preview of the example I used at https://bookdown.org/yihui/bookdown-demo/.
