+*Black* standardizes most numeric literals to use lowercase letters for the
+syntactic parts and uppercase letters for the digits themselves: `0xAB`
 instead of `0XAB` and `1e10` instead of `1E10`. Python 2 long literals are
 styled as `2L` instead of `2l` to avoid confusion between `l` and `1`. In
 Python 3.6+, *Black* adds underscores to long numeric literals to aid
 readability: `100000000` becomes `100_000_000`.
 
+For regions where numerals are grouped differently (like [India](https://en.wikipedia.org/wiki/Indian_numbering_system)
