Personal Access Token (PAT):

• Go to https://github.com/settings/tokens and click “Generate token”.

• Or using the usethis package:

## install if needed:
## install.packages("usethis")

usethis::create_github_token()

Run the following line and paste your PAT

gitcreds::gitcreds_set()

Tell git who you are:

Command line

git config --global user.name 'diegoxx'
git config --global user.email 'diego@example.xx'
git config --global --list

Or:

usethis::use_git_config(user.name = "diegoxx", user.email = "diego@example.xx")
