 #### Custom module values
-Previous versions of `QRCode` held only boolean matrix values that only allowed to determine whether a module was dark or not. Now you can distinguish between different parts of the matrix, namely the several required patterns from the QR Code specification, and use them in different ways.
-
-The dark value is the module (light) value shifted by 8 bits to the left: `$value = $M_TYPE << ($bool ? 8 : 0);`, where `$M_TYPE` is one of the `QRMatrix::M_*` constants.
+You can distinguish between different parts of the matrix, namely the several required patterns from the QR Code specification, and use them in different ways.
+The dark value is the module value (light) shifted by 8 bits to the left: `$value = $M_TYPE << ($bool ? 8 : 0);`, where `$M_TYPE` is one of the `QRMatrix::M_*` constants.
 You can check the value for a type explicitly like...
 ```php
 // for true (dark)
-$value >> 8 === $M_TYPE;
+($value >> 8) === $M_TYPE;
 
-//for false (light)
+// for false (light)
 $value === $M_TYPE;
 ```
 ...or you can perform a loose check, ignoring the module value
 ```php
 // for true
-$value >> 8 > 0;
+($value >> 8) > 0;
 
 // for false
-$value >> 8 === 0
+($value >> 8) === 0;
 ```
