-== Overview
+:doctype:           book
 
-Official low-level client for Elasticsearch. Its goal is to provide common
-ground for all Elasticsearch-related code in Python; because of this it tries
-to be opinion-free and very extendable. The full documentation is available at
-https://elasticsearch-py.readthedocs.io
+include::{asciidoc-dir}/../../shared/attributes.asciidoc[]
 
-=== Installation
+include::overview.asciidoc[]
 
-It can be installed with pip:
-
-[source,sh]
--------------------------------------
-$ python -m pip install elasticsearch
--------------------------------------
-
-If your application uses async/await in Python you can install with
-the `async` extra:
-
-[source,sh]
---------------------------------------------
-$ python -m pip install elasticsearch[async]
---------------------------------------------
-
-Read more about https://elasticsearch-py.readthedocs.io/en/master/async.html[how to use asyncio with this project].
-
-
-=== Compatibility
-
-Current development happens in the master branch.
-
-The library is compatible with all Elasticsearch versions since `0.90.x` but you
-**have to use a matching major version**:
-
-For **Elasticsearch 7.0** and later, use the major version 7 (`7.x.y`) of the
-library.
-
-For **Elasticsearch 6.0** and later, use the major version 6 (``6.x.y`) of the
-library.
-
-For **Elasticsearch 5.0** and later, use the major version 5 (`5.x.y`) of the
-library.
-
-For **Elasticsearch 2.0** and later, use the major version 2 (`2.x.y`) of the
-library, and so on.
-
-The recommended way to set your requirements in your `setup.py` or
-`requirements.txt` is::
-
-    # Elasticsearch 7.x
-    elasticsearch>=7,<8
-
-    # Elasticsearch 6.x
-    elasticsearch>=6,<7
-
-    # Elasticsearch 5.x
-    elasticsearch>=5,<6
-
-    # Elasticsearch 2.x
-    elasticsearch>=2,<3
-
-If you have a need to have multiple versions installed at the same time older
-versions are also released as ``elasticsearch2`` and ``elasticsearch5``.
-
-=== Example use
-
-Simple use-case:
-
-[source,python]
-------------------------------------
->>> from datetime import datetime
->>> from elasticsearch import Elasticsearch
-
-# By default we connect to localhost:9200
->>> es = Elasticsearch()
-
-# Datetimes will be serialized...
->>> es.index(index="my-index-000001", doc_type="test-type", id=42, body={"any": "data", "timestamp": datetime.now()})
-{'_id': '42', '_index': 'my-index-000001', '_type': 'test-type', '_version': 1, 'ok': True}
-
-# ...but not deserialized
->>> es.get(index="my-index-000001", doc_type="test-type", id=42)['_source']
-{'any': 'data', 'timestamp': '2013-05-12T19:45:31.804229'}
-------------------------------------
-
-[NOTE]
-All the API calls map the raw REST API as closely as possible, including
-the distinction between required and optional arguments to the calls. This
-means that the code makes distinction between positional and keyword arguments;
-we, however, recommend that people use keyword arguments for all calls for
-consistency and safety.

-=== Features
-
-The client's features include:
-
-* Translating basic Python data types to and from JSON
-
-* Configurable automatic discovery of cluster nodes
-
-* Persistent connections
-
-* Load balancing (with pluggable selection strategy) across all available nodes
-
-* Failed connection penalization (time based - failed connections won't be
-  retried until a timeout is reached)
-
-* Thread safety
-
-* Pluggable architecture
-
-The client also contains a convenient set of
-https://elasticsearch-py.readthedocs.org/en/master/helpers.html[helpers] for
-some of the more engaging tasks like bulk indexing and reindexing.
-
-
-=== Elasticsearch DSL
-
-For a more high level client library with more limited scope, have a look at
-https://elasticsearch-dsl.readthedocs.org/[elasticsearch-dsl] - a more Pythonic library
-sitting on top of `elasticsearch-py`.
-
-It provides a more convenient and idiomatic way to write and manipulate
-https://elasticsearch-dsl.readthedocs.org/en/latest/search_dsl.html[queries]. It
-stays close to the Elasticsearch JSON DSL, mirroring its terminology and
-structure while exposing the whole range of the DSL from Python either directly
-using defined classes or a queryset-like expressions.
-
-It also provides an optional
-https://elasticsearch-dsl.readthedocs.org/en/latest/persistence.html#doctype[persistence
-layer] for working with documents as Python objects in an ORM-like fashion:
-defining mappings, retrieving and saving documents, wrapping the document data
-in user-defined classes.
