 This package was adapted from [romannumeral](https://github.com/brandenc40/romannumeral) to fit my specific minimal use-case.
 
-All functionality except for the ability to convert integers to **lowercase** roman numerals has been removed.
+All functionality except for the ability to convert integers to roman numerals has been removed.

+Since I have less functionality to worry about, I was also able to implement vinculum notation support to extend the range of supported integers to 3,999,999.
+I also added the ability to choose between uppercase and lowercase roman numerals (optimized for lowercase due to my personal use-case).
 
 If you need any additional functionality or further documentation, please see the original package.
