Help installing Butterflow

[David Herron]

In my experience it's possible to use Homebrew and MacPorts on the same
computer.  In my case I primarily use MacPorts but have a couple things
installed using Homebrew.  Mostly when I install something with Homebrew,
it's because I'm documenting something for my book on Node.js programming
(Node.js Web Development) and the user base needs to know how to deal with
both systems.

For something like this there is another approach that would be useful.

Multipass - https://multipass.run/ - gives you a very light weight full
Ubuntu environment.  You could install Multipass and then follow the Linux
instructions.

Use - multipass launch - to launch an Ubuntu instance.

Use - multipass shell - to get a command shell inside the Ubuntu instance

Use - multipass mount - to mount a directory from your computer inside the
instance

That should be enough to run this tool.
