a few ideas for further improvement after reviewing #157:
[x] before "finding the CLI" instructions for Windows: Explain why we need a Unix Shell.
[x] add keyboard shortcuts to find e.g., the tilde on macOS and Windows
[x] autocompletion: can we use a different example than ls because it's only introduced later?
[x] we have a box about command line history and a section. those should be merged.
For example, typing ls (you will find out more about this command below) and pressing ⇥ Tab might complete it to ls -l or ls -a. Autocompletion also works for the Git commands, that will be introduced in the following chapters of this book.
[x] consistency: sometimes "Git Bash", "GitBASH", "Gitbash" or "Git for Windows" is used. we should make this consistent.
