-```go
-package main
-
-import (
-	"fmt"
-
-	"github.com/gomantics/sx"
-)
-
-func main() {
-	// Convert to different cases
-	fmt.Println(sx.CamelCase("hello-world"))  // helloWorld
-	fmt.Println(sx.PascalCase("hello_world")) // HelloWorld
-	fmt.Println(sx.KebabCase("HelloWorld"))   // hello-world
-	fmt.Println(sx.SnakeCase("HelloWorld"))   // hello_world
-	fmt.Println(sx.TrainCase("hello-world"))  // Hello-World
-	fmt.Println(sx.FlatCase("hello-world"))   // helloworld
-
-	// Works with mixed separators and cases
-	fmt.Println(sx.CamelCase("mixed_caseWith-different.separators")) // mixedCaseWithDifferentSeparators
-
-	// Handle complex acronyms
-	fmt.Println(sx.KebabCase("XMLHttpRequest"))                      // xml-http-request
-	fmt.Println(sx.CamelCase("HTML5Parser", sx.WithNormalize(true))) // html5Parser

-## Case Functions
+**https://gomantics.dev/sx**
 
-- `CamelCase()` - converts to camelCase
-- `PascalCase()` - converts to PascalCase
-- `KebabCase()` - converts to kebab-case
-- `SnakeCase()` - converts to snake_case
-- `TrainCase()` - converts to Train-Case
-- `FlatCase()` - converts to flatcase (no separators)
-
-## Utilities
-
-- `SplitByCase()` - splits strings into words by case changes and separators
-- `UpperFirst()` - capitalizes first character
-- `LowerFirst()` - lowercases first character
-
-## Options
-
-Some functions support options for customization:
+## Quick Example
 
 ```go
-// Normalize case for strict PascalCase/camelCase
-sx.PascalCase("XMLHttpRequest", sx.WithNormalize(true))  // XmlHttpRequest
+import "github.com/gomantics/sx"
 
-// Custom separators for splitting
-sx.SplitByCase("hello.world", sx.WithSeparators('.'))  // ["hello", "world"]
-
-// Custom separator for kebab case
-sx.KebabCase("hello world", "|")  // hello|world
+sx.CamelCase("hello-world")   // helloWorld
+sx.PascalCase("hello_world")  // HelloWorld
+sx.KebabCase("HelloWorld")    // hello-world
+sx.SnakeCase("HelloWorld")    // hello_world
 ```
