Describes how to set up diff-so-fancy

diff-so-fancy-setup.markdown

• Install diff-so-fancy via their website (or just run npm install -g diff-so-fancy)
• Add the following to your .gitconfig file:

[core]
  pager = diff-so-fancy | less --tabs=1,5 -R

• I find that these colors work best with it, but it's up to you if you want to add them to your .gitconfig or not.

[color "diff"]
  meta = "yellow bold"
  commit = "green bold"
  frag = "magenta bold"
  old = "red bold"
  new = "green bold"
  whitespace = "red reverse"
[color "diff-highlight"]
  oldNormal = "red bold"
  oldHighlight = "red bold 52"
  newNormal = "green bold"
  newHighlight = "green bold 22"

What do the "52" and "22" mean?

Those are colors for ANSI 256 (the 8-bit color version of ANSI escape codes). 22 is a dark green and 52 is a dark red. If you're curious, you can learn more here:
