 This might be a good idea to do, if you have several extended classes of the same model and you need hashslugs to be consistent.

-#### Alphabet
+You can set the minimum length of a slug globally too, by adding the following line to `config/hashslug.php`:
+
+```php
+    'minSlugLength' => 10
+```
+
+### Alphabet
 
 The default alphabet is `abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890`
 
 This can be changed:
 
 ```php
 class Post extends Model {
-	use HasHashSlug;
+    use HasHashSlug;
 
-	protected static $alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
+    protected static $alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
