R stats help

Hoping ioplokon might have an idea. Trying to follow the instructions here: https://statsbomb.com/wp-content/uploads/2022/08/Working-with-R.pdf

I get as far as this

install.packages("devtools")
install.packages("remotes")
remotes::install_version("SDMTools", "1.1-221")
Then, to install StatsBombR itself, run:
devtools::install_github("statsbomb/StatsBombR")

And then I get the following error message:

Downloading GitHub repo statsbomb/StatsBombR@HEAD
Error: Failed to install 'StatsBombR' from GitHub:
Git does not seem to be installed on your system.

Suggestions gratefully received
