-> Any git repository may contain tons of information about commits, contributors, and files. Extracting this information is not always trivial, mostly because there are a gadzillion options to a gadzillion git commands – I don’t think there is a single person alive who knows them all. Probably not even [Linus Torvalds](https://github.com/torvalds) himself :).

 ### macOS (homebrew)
 
+macOS requires GNU coreutils to be installed and for the non "g" aliased
+versions to be exported to your path. The following is an example of how to
+perform this if you are using Homebrew as your package manager.
+
+```bash
+brew install coreutils
+export PATH="$HOMEBREW_PREFIX/opt/coreutils/libexec/gnubin:$PATH"
+```
+
+From there, you can install via Homebrew as follows:
+
 ```bash
 brew install git-quick-stats
 ```
 
 Or you can follow the UNIX and Linux instructions if you wish.
 
+If you would like to default to using the GNU coreutils (recommended), then you
+can add `export PATH="$HOMEBREW_PREFIX/opt/coreutils/libexec/gnubin:$PATH"` to
+your applicable `~/.bash_profile`, `~/.zprofile`, or other relevant profile
+based on the shell of your choice.
