 select2entity-bundle
 ====================
 
 ## Introduction
 
 This is a Symfony bundle which enables the popular [Select2](https://select2.github.io) component to be used as a drop-in replacement for a standard entity field on a Symfony form.
 
-It works with Symfony 2, 3 and 4.
+It works with Symfony 4 and 5. For Symfony 2 and 3, please use version or 2.x of the bundle.
+For Select2 4.0 and above. For older versions, use version 1.x of the bundle (not compatible with Symfony 5).
 
 The main feature that this bundle provides compared with the standard Symfony entity field (rendered with a html select) is that the list is retrieved via a remote ajax call. This means that the list can be of almost unlimited size. The only limitation is the performance of the database query or whatever that retrieves the data in the remote web service.

 ## How to use

+The following is for Symfony 4. See https://github.com/tetranz/select2entity-bundle/tree/v2.1 for Symfony 2/3 configuration and use.
 
 Select2Entity is simple to use. In the buildForm method of a form type class, specify `Select2EntityType::class` as the type where you would otherwise use `entity:class`.
