+# Contributing to the Elasticsearch Node.js client
+
+The Elasticsearch Node.js client is open source and we love to receive contributions from our community — you!
+
+There are many ways to contribute,
+from writing tutorials or blog posts,
+improving the documentation,
+submitting bug reports and feature requests or writing code.
+
+## Repository structure
+The `master` branch is considered unstable, and it's compatible with Elasticsearch master. Unless you are patching an issue, new features should always be sent to the `master` branch, in case of a bugfix, it depends if the bug affects all the release lines.<br/>
+There is a branch for every supported release line, such as `7.x` or `6.x`. We release bugfixes as soon as possible, while minor and major releases are published at the same time of the Elastic Stack.
+
+Usually for every release line there will be a *published* version and a *next* version. Eg: the `7.x` branch contains the version published on npm, and bugfixes should be sent there, while `7.2` *(assuming that 7.1.x is released)* contains the next version, and new features should be sent there.
+
+## Code contributions
+
+If you have a bugfix or new feature that you would like to contribute,
+please find or open an issue about it first.
+Talk about what you would like to do.
+It may be that somebody is already working on it,
+or that there are particular issues that you should know about before implementing the change.
+
+Note that we strictly follow the [Elastic EOL schedule](https://www.elastic.co/support/eol).
+
+### Submitting your changes
+
+Generally, we require that you test any code you are adding or modifying.
+Once your changes are ready to submit for review:
+
+1. Test your changes
+
+    Run the test suite to make sure that nothing is broken.
+    Usually run `npm test` is enough, our CI will take care of running the integration test. If you want to run the integration test yourself, see the *Testing* section below.
+
+2. Submit a pull request
+
+    Push your local changes to your forked copy of the repository and [submit a pull request](https://help.github.com/articles/using-pull-requests).
+    In the pull request,
+    choose a title which sums up the changes that you have made,
+    and in the body provide more details about what your changes do.
+    Also mention the number of the issue where discussion has taken place,
+    eg "Closes #123".
+
+3. Sign the Contributor License Agreement
+
+    Please make sure you have signed our [Contributor License Agreement](https://www.elastic.co/contributor-agreement/).
+    We are not asking you to assign copyright to us,
+    but to give us the right to distribute your code without restriction.
+    We ask this of all contributors in order to assure our users of the origin and continuing existence of the code.
+    You only need to sign the CLA once.
+
+4. Be patient
+
+    We might not be able to review your code as fast as we would like to,
+    but we'll do our best to dedicate it the attention it deserves.
+    Your effort is much appreciated!
+
+### Code generation
+
+The entire content of the API folder is generated as well as the `docs/reference.asciidoc` file.<br/>
+If you want to run the code generation you should run the following command:
+```sh
+node scripts/generate --tag <tag name>
+# or
+node scripts/generate --branch <branch name>
+```
+Then you should copy the content of `api/generated.d.ts` into the `index.d.ts` file *(automate this step would be a nice pr!)*.
+
+### Testing
+There are different test scripts, usually during development you only need to run `npm test`, but if you want you can run just a part of the suite, following you will find all the testing scripts and what they do.
+
+| Script | Description |
+|---|---|
+| `npm run test:unit` | Runs the content of the `test/unit` folder. |
+| `npm run test:behavior` | Runs the content of the `test/behavior` folder. |
+| `npm run test:types` | Runs the content of the `test/types` folder. |
+| `npm run test:unit -- --cov --coverage-report=html` | Runs the content of the `test/unit` folder and calculates the code coverage. |
+| `npm run test:integration` | Runs the integration test runner.<br/>*Note: it requires a living instance of Elasticsearch.* |
+| `npm run lint` | Run the [linter](https://standardjs.com/). |
+| `npm run lint:fix` | Fixes the lint errors. |
+| `npm test` | Runs lint, unit, behavior, and types test. |
+
+#### Integration test
+The integration test are generated on the fly by the runner you will find inside `test/integration`, once you execute it, it will clone the Elasticsearch repository and checkout the correct version to grab the [OSS yaml files](https://github.com/elastic/elasticsearch/tree/master/rest-api-spec/src/main/resources/rest-api-spec/test) and the [Elastic licensed yaml files](https://github.com/elastic/elasticsearch/tree/master/x-pack/plugin/src/test/resources/rest-api-spec/test) that will be used for generating the test.
+
+Usually this step is executed by CI since it takes some time, but you can easily run this yourself! Just follow this steps:
+1. Boot an Elasticsearch instance, you can do that by running `./scripts/es-docker.sh` or `./scripts/es-docker-platinum.sh`, the first one will work only with the OSS APIs, while the second will work also with the Elastic licensed APIs;
+1. If you are running the OSS test, you should use `npm run test:integration`, otherwise use `TEST_ES_SERVER=https://elastic:changeme@localhost:9200 npm run test:integration`. You can also pass a `-b` parameter if you want the test to bail out at the first failure: `npm run test:integration -- -b`;
+1. Grab a coffee, it will take some time ;)
+
+### Releasing
+
+If you have access to make releases, the process is as follows:
+
+1. Update the version in `package.json` according to the scale of the change. (major, minor or patch)
+1. Commit changes with message `Bumped vx.y.z` where `x.y.z` is the version in `package.json`
+1. Create a release via the GitHub UI.
+1. Wait for CI to finish running the test.
+1. Publish to npm with `npm publish` *(see [publish](https://docs.npmjs.com/cli/publish) and [dist-tag](https://docs.npmjs.com/cli/dist-tag) docs)*

 ### Compatibility
 
----
+The minimum supported version of Node.js is `v8`.
 
-**Warning:** currently on npm you will only find a beta release that works with Elasticsearch 7, we will add the support for Elasticsearch 5, 6, and 7 once we release the final version of this library.
+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`          |
+| `6.x`                 | `6.x`          |
+| `5.x`                 | `5.x`          |
 
-The library is compatible with all Elasticsearch versions since 5.x, but you should use the same major version of the Elasticsearch instance that you are using.
+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
+npm install @elastic/elasticsearch@<major>
 ```
 
-## Usage
-You can find the full documentation in the [docs](https://github.com/elastic/elasticsearch-js/tree/master/docs) folder.
+#### Browser
+
+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.

+## 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: { foo: 'bar' }
+  body: {
+    query: {
+      match: { hello: 'world' }
+    }
+  }
 })
 
 // callback API
 client.search({
   index: 'my-index',
-  body: { foo: 'bar' }
+  body: {
+    query: {
+      match: { hello: 'world' }
+    }
+  }
 }, (err, result) => {

+
+Let's see a complete example!
+```js
+'use strict'
+
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({ node: 'http://localhost:9200' })
+
+async function run () {
+  // Let's start by indexing some data
+  await client.index({
+    index: 'game-of-thrones',
+    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
+    body: {
+      character: 'Ned Stark',
+      quote: 'Winter is coming.'
+    }
+  })
+
+  await client.index({
+    index: 'game-of-thrones',
+    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
+    body: {
+      character: 'Daenerys Targaryen',
+      quote: 'I am the blood of the dragon.'
+    }
+  })
+
+  await client.index({
+    index: 'game-of-thrones',
+    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
+    body: {
+      character: 'Tyrion Lannister',
+      quote: 'A mind needs books like a sword needs a whetstone.'
+    }
+  })
+
+  // here we are forcing an index refresh, otherwise we will not
+  // get any result in the consequent search

+
+  // Let's search!
+  const { body } = await client.search({
+    index: 'game-of-thrones',
+    // type: '_doc', // uncomment this line if you are using Elasticsearch ≤ 6
+    body: {
+      query: {
+        match: { quote: 'winter' }

+    }
+  })
+
+  console.log(body.hits.hits)
 }
+

-### Request specific options
-If needed you can pass request specific options in a second object:
-```js
-// promise API
-const result = await client.search({
-  index: 'my-index',
-  body: { foo: 'bar' }
-}, {
-  ignore: [404],
-  maxRetries: 3
-})
+## 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.
+
+The command you must run to install different version of the client is:
+```sh
+npm install <alias>@npm:@elastic/elasticsearch@<version>
 ```
-The supported *request specific options* are:
-```ts
-{
-  ignore: [number], // default `null`
-  requestTimeout: number, // client default
-  maxRetries: number, // default `5`
-  asStream: boolean, // default `false`
-  compression: string, // default `false`
-  headers: object, // default `null`
-  querystring: object // default `null`
+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"
 }
 ```
+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')
+
+const client6 = new Client6({ node: 'http://localhost:9200' })
+const client7 = new Client7({ node: 'http://localhost:9201' })
+
+client6.info(console.log)
+client7.info(console.log)
+```
+
+Finally, if you want to install the client for the next version of Elasticsearch *(the one that lives in Elasticsearch’s master branch)*, you can use the following command:
+```sh
+npm install esmaster@github:elastic/elasticsearch-js
+```
