-In this JavaScript example, we can see:
+^ Difftastic understands exactly which pieces of syntax has changed,
+and can highlight them in context.
 
-(1) Difftastic understands nesting. It highlights the matching `{` and
-`}`, but understands that `foo()` hasn't changed despite the leading
-whitespace.

-(2) Difftastic understands which lines should be aligned. It's aligned
-`bar(1)` on the left with `bar(2)` on the right, even though the
-textual content isn't identical.
+^ Difftastic understands when whitespace matters, and when it's just
+an indentation change.
 
-(3) Difftastic understands that line-wrapping isn't
-meaningful. `"eric"` is now on a new line, but it hasn't changed.

+^ Difftastic is not line-oriented. If you reformat your code and it's
+now split over multiple lines, difftastic will show you what's
+actually changed.

 ## FAQ
 
-### Isn't this basically `--word-diff --ignore-all-space`?

-Word diffing [can't do

-Difftastic parses your code. It understands when whitespace matters,
-such as inside string literals or languages like Python. It understands
-that `x-1` is three tokens in JS but one token in Lisp.
