setup instructions for macOS to include homebrew option?

Do users think that there's any mileage in introducing a homebrew (https://brew.sh) install option for some of the macOS components? This occurred to me when assisting in a recent Unix class where a user was running macOS 10.14 Mojave and received a rather cryptic message when trying to run the `git` command. (It used to be that a more helpful message concerning the installation of the _Command Line Tools_ appeared.)

However, all of the following _could_ be installed via homebrew and avoid the need for Anaconda (although I understand that there is a credible argument for using the same system across different platforms):

* git
* python 3 (inc pip). This is particularly important for macOS as (as of writing) the bundled system version is still `2.7.10`.
* iPython

Homebrew also handles the installation of the _Command Line Tools_, if they're required.
