+## Alternatives
+
+Recently I've released a new Elasticsearch ecosystem for Laravel, it includes:
+
+* [Elastic Scout](https://github.com/babenkoivan/elastic-scout-driver) - a generic Elasticsearch driver for Laravel Scout.
+It's perfect, if you need to build a simple search in your Laravel application. 
+* [Elastic Scout Driver](https://github.com/babenkoivan/elastic-scout-driver) - an extension for Elastic Scout.
+If you want to take advantage of such Elasticsearch features as bool queries, highlighting, etc., it's a way to go.
+* [Elastic Migrations](https://github.com/babenkoivan/elastic-migrations) - an easy way to create, delete or update 
+Elasticsearch index schema and share it with your teammates. It has quite similar interface to Laravel database migrations.
+
+If any of it sounds interesting to you and you want to get more details, please read 
+[The Ultimate Guide to Elasticsearch in Laravel Application](https://itnext.io/the-ultimate-guide-to-elasticsearch-in-laravel-application-ee636b79419c). 
+The article makes a good overview of the mentioned packages and provides usage examples.
+
+FAQ:
+* Why did you create a new package instead of a new `scout-elasticsearch-driver` version? - I didn't want to create another 
+all in one package for obvious reasons: no separation of concerns, not compatible with other Scout drivers, hard to test
+and develop, etc. As [Elastic Scout](https://github.com/babenkoivan/elastic-scout-driver) is a generic driver and
+doesn't implement all the `scout-elasticsearch-driver` features, it would be wrong to call it a new `scout-elasticsearch-driver` 
+version.   
+* What does it mean for scout-elasticsearch-driver? - Well, it's maintained by the community at the moment 
+(thank you @iget-esoares and @lucamichot for keeping the project alive 🎉). I hope they will continue contributing to the 
+project and bring a new version of `scout-elasticsearch-driver` in the future.
