Welcome!
This is a minimal example of a book based on R Markdown and bookdown (https://github.com/rstudio/bookdown).
This template provides a skeleton file structure that you can edit to create your book.
The contents inside the .Rmd files provide some pointers to help you get started, but feel free to also delete the content in each file and start fresh.
Additional resources:
The bookdown book: https://bookdown.org/yihui/bookdown/
The bookdown package reference site: https://pkgs.rstudio.com/bookdown
Eventually this will be my PhD thesis.
