Issue description

item 4.2 suggests using vscodium or Gedit (sic) whereas vscodium is not discussed further until chapter 6. Then in the note in item 4.3 it gives an example using vim.

A small section on different editor choices here might suffice but if there is an expectation to use vim/gedit/vscodium/nano then it should include basic information about removing tabs and dealing with indentation.

Given the importance of the student's choice of editor going forward, especially in follow up classes, a small summary on the various editors available in the classroom might allow them to make some early choices, or recognise that they need additional editor skills - e.g. check out vimtutor etc
