git

git is a version control software. With it, you can download repositories, track your changes and develop code collaboratively.

This needs to be done only once :)

If not already done before: create a github account at https://github.com/signup. Use a short username!
Download and install git, see https://git-scm.com/downloads
Restart RStudio (if open)
Manage authentification without renewing PAT access tokes via SSH (screenshots for these instructions, if wanted):
- RStudio -> Tools -> Global Options -> Git/SVN: Ensure the path to the Git executable is correct.
- Create SSH Key, close window
- View public key: copy the displayed public key
- go to https://github.com/settings/keys and click New SSH key, name it and paste the public key
- in the RStudio bottom/left Tab Terminal: type the following (line by line):
```
git version # just to see git works fine
git config --global user.email "Your_Email_Used_For_Github@domain.com"
git config --global user.name "Your_Github_UserName_Here"
```

To clone a git repo, RStudio handles most the work for you :)

1. Go to a repo (for example github.com/brry/fpsetup) and click on Code - SSH (if logged in) - Copy URL

1. At RStudio - File - New Project - Version Control - Git,
  paste the repository URL, set the subdirectory and create project.
  I recommend to keep the Project directory name so local and github folder names match exactly.
