 Setup

 Run the rails generator
 
-    rails generate devise_ldap_authenticatable:install
+    rails generate devise_ldap_authenticatable:install [options]
 
 This will install the sample.yml, update the devise.rb initializer, and update your user model. There are some options you can pass to it:
 
-    [--user-model=USER_MODEL]  # Model to update
-                               # Default: user
-    [--update-model]           # Update model to change from database_authenticatable to ldap_authenticatable
-                               # Default: true
-    [--add-rescue]             # Update Application Controller with resuce_from for DeviseLdapAuthenticatable::LdapException
