Ideas #18

Add topics that beginners might be interested in.

• Configure preferred editor (not everyone loves vim like I do... GASP)
• Create aliases. For example,

  git log --all --decorate --graph --oneline
  git config --global alias.graph 'log --all --decorate --graph --oneline'
  git graph
  

Remove more advanced topics (or too deep of topics).

• super advanced staging stuff
