 The same structure can be adopted for the other algorithms, not just for PBKDF2.
 
 #### Customize Password.*hash*()
 If you need to add a new method in the chain of parameters or want to override one, here's the fastest way:
 ```java
-Password.hash("password", CustomBuilder::new).withSalt("fixed salt").withOtherStuff().withBCrypt();
+Password.hash("password", CustomBuilder::new).addSalt("fixed salt").withOtherStuff().withBCrypt();
 ```
 ```java
 public class CustomBuilder extends HashBuilder<CustomBuilder> {
