+**!! Gem under development before public release !!**
+
+Caoutsearch is a new Elasticsearch integration for Ruby and/or Rails.  
+It provides a simple but powerful DSL to perform complex indexing and searching, while securely exposing search criteria to a public and chainable API, without overwhelming your models.
+
+Caoutsearch only supports Elasticsearch 8.x right now.  
+It is used in production in a robust application, updated and maintained for several years at [Solutions & Territoire](https://solutions-territoire.fr).
+
+Caoutsearch was inspired by awesome gems such as [elasticsearch-rails](https://github.com/elastic/elasticsearch-rails) or [search_flip](https://github.com/mrkamel/search_flip).  
+Depending on your search scenarios, they may better suite your needs.
+
+## Overview
+
+Caoutsearch let you create `Index` and `Search` classes to manipulate your data :
+
+```ruby
+class ArticleIndex < Caoutsearch::Index::Base
+  property :title
+  property :published_on
+  property :tags
+
+  def tags
+    records.tags.public.map(&:to_s)
+  end
+end
+```
+
+```ruby
+class ArticleSearch < Caoutsearch::Search::Base
+  filter :title, as: :match
+  filter :published_on, as: :date
+  filter :tags
+
+  has_aggregation :popular_tags, {
+    filter: { term: { published: true } },
+    aggs: {
+      published: {
+        terms: { field: :tags, size: 10 }
+      }
+    }
+  }
+end
+```
+
+You can then index your records
+
+```ruby
+ArticleIndex.reindex
+```
+
+Or search through them:
+
+```ruby
+ArticleSearch.search(published_on: [["now-1y", nil]]).aggregate(:popular_tags)
+```
