 ### Compatibility
 
-Language clients are forward compatible; meaning that clients support communicating with greater or equal minor versions of Elasticsearch.
+The library is compatible with all Elasticsearch versions since 5.x, and you should use the same major version of the Elasticsearch instance that you are using.
-Elasticsearch language clients are only backwards compatible with default distributions and without guarantees made.

 ## Quick start
 
+First of all, require the client and initialize it:
+```js
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({ node: 'http://localhost:9200' })
+```
+
+You can use both the callback-style API and the promise-style API, both behave the same way.
+```js
+// promise API
+const result = await client.search({
+  index: 'my-index',
+  body: {
+    query: {
+      match: { hello: 'world' }
+    }
+  }
+})
+
+// callback API
+client.search({
+  index: 'my-index',
+  body: {
+    query: {
+      match: { hello: 'world' }
+    }
+  }
+}, (err, result) => {
+  if (err) console.log(err)
+})
+```
+The returned value of **every** API call is formed as follows:
+```ts
+{
+  body: object | boolean
+  statusCode: number
+  headers: object
+  warnings: [string]
+  meta: object
+}
+```
+
+Let's see a complete example!
 ```js
 'use strict'
 
 const { Client } = require('@elastic/elasticsearch')
-const client = new Client({
+const client = new Client({ node: 'http://localhost:9200' })
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
 
 async function run () {
   // Let's start by indexing some data
   await client.index({
     index: 'game-of-thrones',
-    document: {
+    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
+    body: {
       character: 'Ned Stark',
       quote: 'Winter is coming.'
     }

-=== Advanced configuration
-
-If you need to customize the client behavior heavily, you are in the right 
-place! The client enables you to customize the following internals:
-
-* `ConnectionPool` class
-* `Connection` class
-* `Serializer` class
-
-NOTE: For information about the `Transport` class, refer to <<transport>>.
-
-
-[discrete]
-==== `ConnectionPool`
-
-This class is responsible for keeping in memory all the {es} Connection that you 
-are using. There is a single Connection for every node. The connection pool 
-handles the resurrection strategies and the updates of the pool.
-
-[source,js]
-----
-const { Client, ConnectionPool } = require('@elastic/elasticsearch')
-
-class MyConnectionPool extends ConnectionPool {
-  markAlive (connection) {
-    // your code
-    super.markAlive(connection)
-  }
-}
-
-const client = new Client({
-  ConnectionPool: MyConnectionPool,
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-----
-
-
-[discrete]
-==== `Connection`
-
-This class represents a single node, it holds every information we have on the 
-node, such as roles, id, URL, custom headers and so on. The actual HTTP request 
-is performed here, this means that if you want to swap the default HTTP client 
-(Node.js core), you should override the `request` method of this class.
-
-[source,js]
-----
-const { Client, BaseConnection } = require('@elastic/elasticsearch')
-
-class MyConnection extends BaseConnection {
-  request (params, callback) {
-    // your code
-  }
-}
-
-const client = new Client({
-  Connection: MyConnection,
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-----
-
-
-[discrete]
-==== `Serializer`
-
-This class is responsible for the serialization of every request, it offers the 
-following methods:
-
-* `serialize(object: any): string;` serializes request objects.
-* `deserialize(json: string): any;` deserializes response strings.
-* `ndserialize(array: any[]): string;` serializes bulk request objects.
-* `qserialize(object: any): string;` serializes request query parameters.
-
-[source,js]
-----
-const { Client, Serializer } = require('@elastic/elasticsearch')
-
-class MySerializer extends Serializer {
-  serialize (object) {
-    // your code
-  }
-}
-
-const client = new Client({
-  Serializer: MySerializer,
-  cloud: { id: '<cloud-id>' },
-  auth: { apiKey: 'base64EncodedKey' }
-})
-----
-
-[discrete]
-==== Migrate to v8
-
-The Node.js client can be configured to emit an HTTP header
-`Accept: application/vnd.elasticsearch+json; compatible-with=7`
-which signals to Elasticsearch that the client is requesting
-`7.x` version of request and response bodies. This allows for
-upgrading from 7.x to 8.x version of Elasticsearch without upgrading
-everything at once. Elasticsearch should be upgraded first after
-the compatibility header is configured and clients should be upgraded
-second.
-To enable to setting, configure the environment variable
-`ELASTIC_CLIENT_APIVERSIONING` to `true`.
