 We like this because Git for Windows leaves the Git executable in a conventional location, which will help you and other programs, e.g. RStudio, find it and use it. This also supports a transition to more expert use, because the "Git Bash" shell will be useful as you venture outside of R/RStudio.
 
-  *  **NOTE:** Select "Use Git from the Windows Command Prompt" during installation. Otherwise, we believe it's OK to accept the defaults.
+  *  **NOTE:** When asked about "Adjusting your PATH environment", make sure to select "Git from the command line and also from 3rd-party software". Otherwise, we believe it is good to accept the defaults.
   * Note that RStudio for Windows prefers for Git to be installed below `C:/Program Files` and this appears to be the default. This implies, for example, that the Git executable on my Windows system is found at `C:/Program Files/Git/bin/git.exe`. Unless you have specific reasons to otherwise, follow this convention.
 
 This also leaves you with a Git client, though not a very good one. So check out Git clients we recommend (chapter \@ref(git-client)).
