 # CapitalizePersonalNamesWithStringy
-A PHP library that helps you capitalize personal names
+A PHP library that helps you capitalize personal names. Extends [Stringy](https://github.com/danielstjules/Stringy), a PHP string manipulation library with multibyte support.
+
+Personal names such as "Marcus Aurelius" are sometimes typed incorrectly using lowercase ("marcus aurelius").
+
+Capitalizing "marcus aurelius" is a simple task. But some names are less simple. Consider "Zeno of Citium". If you have the string "zeno of citium", you should capitalize "zeno" and "citium", but not "of".
+
+CapitalizePersonalNamesWithStringy helps you capitalize personal names by checking against a list of special cases that shouldn't be capitalized. If the name is in the list, it isn't capitalized.
+
+
