You can save a little bit of copy-paste that will take a few minutes at most. If you do it, you can work directly with your own files, work offline, control the hardware, etc. I think it's simpler than this guide makes out too, as it tries to minimise the amount of space used, which is often not needed. Installing Anaconda instead of Miniconda would get you pretty much set up in one step, plus a single copy-paste step if you want all the packages the book uses.
