Hi, due to a question in #IRC I realized that some people are not aware
of the package management features of Emacs. Of course it's covered in
the manual but I think we can mention it in the tutorial. Elpa and
NonGnu are pre-configured so a beginner user should feel comfortable
installing packages from there. 

Attaches is a patch with a short section about package installation and
deletion. Modified the English version.

Best,
