I disagree on not using the cli for installing things etc. Instructions on commands are much easier than instruction about the gui, because they are easily copy pastable.

One example i encounter quite a bit, the instructions for installing python and packages for building cython modules. I have students who are very much intermediate Windows users, but explaining to them how to get the development (they need python for experiment control and analysis) environment going is really painful. They often take days to get in going. On the other hand Linux users are much easier, I just give them the commands to install the packages in an email.
