 ## Usage

 ### Pipeline Operations
 
 Pipeline operations are functions that take an input and return a processed value. Each operation can receive up to four parameters:
+
 - `$input`: The value being processed
 - `$next`: A callback to pass the value to the next operation
 - `$return`: (Optional) A callback to exit the pipeline early with a value
 - `$context`: (Optional) A shared context object passed to all operations
 
 #### Basic Operation Example

 Let's build an input sanitization pipeline:

 ```php
 // String sanitization pipeline
 $sanitizer = zenpipe()
