How can I use the new bs4() theme in bookdown?

Question

How can I use the bs4 theme in bookdown, such as the one used for the R4DS book

In the _output.yaml I see the following code, but it doesn't work with my project.

bookdown::bs4_book:
  theme:
    primary: "#637238"
  repo: https://github.com/hadley/r4ds
  includes:
    in_header: [ga_script.html]

and I get this error when I attempt to build the book

Error: 'bs4_book' is not an exported object from 'namespace:bookdown'
Execution halted

By installating the development version from the github repo.: https://github.com/rstudio/bookdown — Dirk Eddelbuettel, Nov 10 '20 at 23:50
Did you install the `R4DS` package that contains the code for the book format? you can install it by `devtools::install_github("hadley/r4ds")` — Daniel_j_iii, Nov 11 '20 at 02:18

I got it to work by doing the following:

Run the following

remotes::install_github("rstudio/bslib")
install.packages("downlit")
remotes::install_github("rstudio/bookdown")

Change the _output.yaml to the following:

bookdown::bs4_book:
  theme:
    primary: "#637238"

`bookdown` for building the document, `bslib` for the `bookdown::bs4_book` itself and `downlit` because of `Error: Must install the following packages to use bs4_book() * downlit`. – Trusky Nov 21 '20 at 19:12

I think that the following line is enough, `devtools::install_github('rstudio/bookdown@bs4-book-encoding', force = TRUE)` – R.Andres Castaneda Jan 06 '21 at 21:30
