Closes issue #1032.

In episode 4 learners have to use the nano and cat commands for the first time (and will keep using them throughout the lesson). However, there are little explanations currently introducing these commands, in particular nano that can be overwhelming at first usage. This PR adapted the instructions to include a more detailed presentation of both commands and why they are relevant here.
