+### Changing the Hashid column
+To customize the hashid column, set your own custom `$hashidColumn` value on your model.
+```php
+class Receipt extends Model
+{
+    use Hashid;
+
+    protected static $hashidColumn = 'uid';
+}
+```
+
+### Changing the salt
+Each model's table name is by default used as the salt for generating Hashids.
+With that, models of separate classes that share the same IDs 
+(e.g. a `Task` model with ID of 1 and a `Receipt` model also with ID of 1) would each have different Hashids.
+You may change this behaviour and override the salt by specifying the `$hashidSlat` on your model.
+ ```php
+ class Receipt extends Model
+ {
+     use Hashid;
+
+     protected static $hashidSalt = 'salt and pepper';
+ }
+ ```
+
 ### Creating your own Hashids instance
 To fully customize the behaviour of the underlying Hashids library, 
 you may also define your own `Hashids` instance in your model's boot method.
