 Stringy
 =======
 
-A PHP library with a variety of string manipulation methods.
+A PHP library with a variety of multibyte string manipulation functions.
+
+Usage
+-----
+
+```php
+use Stringy\Stringy as S;
+```
+
+**upperCaseFirst**
+
+S::upperCaseFirst($string [, $encoding])
+
+Converts the first character of the supplied string to upper case, with
+support for multibyte strings.
+
+```php
+S::upperCaseFirst('σ test', 'UTF-8');  // 'Σ test'
+```
+
+**lowerCaseFirst**
+
+S::lowerCaseFirst($string [, $encoding])
+
+Converts the first character of the supplied string to lower case, with
+support for multibyte strings.
+
+```php
+S::lowerCaseFirst('Σ test', 'UTF-8');  // 'σ test'
+```
+
+**camelize**
+
+S::camelize($string [, $encoding])
+
+Returns a camelCase version of a supplied string, with multibyte support.
+Trims surrounding spaces, capitalizes letters following digits, spaces,
+dashes and underscores, and removes spaces, dashes, underscores.
+
+```php
+S::camelize('Camel-Case');  // 'camelCase'
+```
+
+**upperCamelize**
+
+S::upperCamelize($string [, $encoding])
+
+Returns an UpperCamelCase version of a supplied string, with multibyte
+support. Trims surrounding spaces, capitalizes letters following digits,
+spaces, dashes and underscores, and removes spaces, dashes, underscores.
+
+```php
+S::upperCamelize('Upper Camel-Case');  // 'UpperCamelCase'
+```
