 At some occasions you know that user-submitted data or other super-global inputs might contain sensitive data. In these cases you do not need to hide the actual value, but you can address the input array instead. In this example we are going to mask the "password" POST value:
 ```php
-	use \Fuko\Masked\Protect;
-
-	Protect::hideInput('password', INPUT_POST);
-
-	// later you need to do a dump of $_POST and ...
-	$_POST_redacted = Protect::protect($_POST);
-	/* ... and the output is
-	Array
-	(
-	    [email] => Bob@sundance.org
-	    [password] => ███████
-	)
-	*/
+use \Fuko\Masked\Protect;
+
+Protect::hideInput('password', INPUT_POST);
+
+// later you need to do a dump of $_POST and ...
+$_POST_redacted = Protect::protect($_POST);
+/* ... and the output is
+Array
+(
+    [email] => Bob@sundance.kid
+    [password] => ███████
+)
+*/
 ```
 
 ## Different Masking
 
 You can use `\Fuko\Masked\Redact` in your project as the library for masking data. By default the class uses `\Fuko\Masked\Redact::disguise()` method for masking, with default settings that masks everything and that uses `█` as masking symbol. Here's how you can change its behaviour:
 ```php
-	use \Fuko\Masked\Redact;
+use \Fuko\Masked\Redact;
 
-	/* leave 4 chars unmasked at the end, and use '*' as masking symbol */
-	Redact::setRedactCallback( [Redact::class, 'disguise'], [4, '*']);
-	echo Redact::redact('1234567890'); // Output is '******7890'
+/* leave 4 chars unmasked at the end, and use '*' as masking symbol */
+Redact::setRedactCallback( [Redact::class, 'disguise'], [4, '*']);
+echo Redact::redact('1234567890'); // Output is '******7890'
 
-	/* leave 4 chars unmasked at the beginning, and use '🤐' as masking symbol */
-	Redact::setRedactCallback( [Redact::class, 'disguise'], [-4, '🤐']);
-	echo Redact::redact('1234567890'); // Output is '1234🤐🤐🤐🤐🤐🤐'
+/* leave 4 chars unmasked at the beginning, and use '🤐' as masking symbol */
+Redact::setRedactCallback( [Redact::class, 'disguise'], [-4, '🤐']);
+echo Redact::redact('1234567890'); // Output is '1234🤐🤐🤐🤐🤐🤐'
 ```
 
 You can set your own callback for masking with `\Fuko\Masked\Redact` class:
 ```php
-	use \Fuko\Masked\Redact;
+use \Fuko\Masked\Redact;
 
-	Redact::setRedactCallback( function($var) { return '💩'; } );
-	echo Redact::redact('1234567890'); // Output is '💩'
+Redact::setRedactCallback( function($var) { return '💩'; } );
+echo Redact::redact('1234567890'); // Output is '💩'
 ```
