Add more anaconda context

[elliewix]

Anaconda is mentioned as a package manager without much context. Not that we need to dive into it that deeply, but I've found it worthwhile to mention that you won't directly use anaconda as an application. It installs things in the background so that commands are mostly standardized across platforms. So you'll be using anaconda pretty much anytime you run python, but it won't look like it.

I've had students skip the anaconda install and seriously question why they did it because they weren't seeing it used later on.
