4.1.2 Set up minimal newbie environment

I think learning a computer system is like learning a new foreign language. Although tutorial books are helpful, you have to practice it with helper tools. In this context, I think it is a good idea to install few additional packages such as mc, vim, lynx, doc-linux-text, and debian-policy. [6]

     # apt-get update
      ...
     # apt-get install mc vim lynx doc-linux-text debian-policy 
      ...

If you already had these packages installed, nothing will be installed.
