-MultiStringReplace.replace("The quick brown fox jumps over the lazy dog brown", {'brown' => 'black', 'fox' => ->() { "cat" }})
+MultiStringReplace.replace("The quick brown fox jumps over the lazy dog brown", {'brown' => 'black', 'fox' => ->(s, e) { "cat" }})
 ```
 
 Also adds a mreplace method to String which does the same thing:
 
 ```ruby
-"The quick brown fox jumps over the lazy dog brown".mreplace({'brown' => 'black', 'fox' => ->() { "cat" }})
+"The quick brown fox jumps over the lazy dog brown".mreplace({'brown' => 'black', 'fox' => ->(_, _) { "cat" }})
 ```
