 - Generalized, pluggable architecture.
 - Configurable, automatic discovery of cluster nodes.
 - Persistent, Keep-Alive connections.
-- Load balancing (with pluggable selection strategy) across all available nodes.

+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 Version | Client Version |
+| --------------------- |----------------|
+| `master`              | `master`       |
+| `7.x`                 | `7.x`          |

+| `5.x`                 | `5.x`          |
+
+To install a specific major of the client, run the following command:
 ```
-# Elasticsearch 7.x
-@elastic/elasticsearch@7
-
-# Elasticsearch 6.x
-@elastic/elasticsearch@6
-
-# Elasticsearch 5.x
-@elastic/elasticsearch@5

-#### Install multiple versions
-If you are using multiple versions of Elasticsearch, you need to use multiple versions of the client. In the past, install multiple versions of the same package was not possible, but with `npm v6.9`, you can do that via aliasing.
+#### Browser
 
-The command you must run to install different version of the client is:
-```sh
-npm install <alias>@npm:@elastic/elasticsearch@<version>
-```
-So for example if you need to install `7.x` and `6.x`, you will run
-```sh
-npm install es6@npm:@elastic/elasticsearch@6
-npm install es7@npm:@elastic/elasticsearch@7
-```
-And your `package.json` will look like the following:
-```json
-"dependencies": {
-  "es6": "npm:@elastic/elasticsearch@^6.7.0",
-  "es7": "npm:@elastic/elasticsearch@^7.0.0"
-}
-```
-And finally, you will require the packages from your code by using the alias you have defined.
-```js
-const { Client: Client6 } = require('es6')
-const { Client: Client7 } = require('es7')
+WARNING: There is no official support for the browser environment. It exposes your Elasticsearch instance to everyone, which could lead to security issues.
+We recommend that you write a lightweight proxy that uses this client instead.

-You can find the full documentation in our [docs](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/index.html) website.
+## 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',

-### Client options
 
-The client is designed to be easily configured as you see fit for your needs, following you can see all the possible options that you can use to configure it.
-
-```ts
-{
