-### Piping Example
-
-Ada can process URLs from piped input, making it easy to integrate with other command-line tools that produce ASCII or UTF-8 outputs. Here's an example of how to pipe the output of another command into Ada. Given a list of URLs, one by line, we may query the normalized URL string (`href`) and detect any malformed URL:

 If you omit `-g`, it will only provide a list of invalid URLs. This might be
 useful if you want to valid quickly a list of URLs.
 
+### Benchmark Runner
 
 The benchmark flag can be used to output the time it takes to process piped input:
 
 ```bash
