 ### 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!)*.
+The entire content of the `src/api/` directory is automatically generated from [the Elasticsearch specification](https://github.com/elastic/elasticsearch-specification), as is the `docs/reference.asciidoc` file.
+This code generation is done using a separate repository that is not currently available to the public.
+
+If you find discrepancies between this client's API code and what you see when actually interacting with an Elasticsearch API, you can open a pull request here to fix it.
+For API fixes, it's likely a change will need to be made to the specification as well, to ensure your fix is not undone by the code generation process.
+We will do our best to make sure this is addressed when reviewing and merging your changes.
+
+PRs to improve the specification are also welcome!
+It is implemented in TypeScript, so JavaScript devs should be able to understand it fairly easily.
+Spec fixes are particularly helpful, as they will be reflected in ALL official Elasticsearch clients, not just this one.

 #### 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 ;)
+The integration tests are generated on the fly by the runner you will find inside `test/integration`.
+Once you execute it, it will fetch the [YAML REST test files](https://github.com/elastic/elasticsearch/tree/main/rest-api-spec/src/yamlRestTest/resources/rest-api-spec/test) from our artifacts API.
+These are used to generate the integration tests.
+
+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 a fresh Elasticsearch instance, which can be done in a Docker container by running `STACK_VERSION=8.10.0 DETACH=true .buildkite/run-elasticsearch.sh`, where `STACK_VERSION` and `DETACH` environment variables can be adjusted to your needs. A `TEST_SUITE` env var can also be set to `free` or `platinum`, and defaults to `free`.
+1. Run `npm run test:integration` to run the whole suite, or `npm run test:integration -- --bail` to stop after the first failure.
+1. Grab a coffee, it will take some time. ;)
+
+This suite is very large, and not all tests will pass.
+This is fine.
+This suite is mostly used to identify notable changes in success/fail rate over time as we make changes to the client.

+## Installation
 
-## Install
-```
-npm install @elastic/elasticsearch
-```
+Refer to the [Installation section](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/getting-started-js.html#_installation)
+of the getting started documentation.
+
+## Connecting
+
+Refer to the [Connecting section](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/getting-started-js.html#_connecting)
+of the getting started documentation.
+
+## Compatibility
+
+The Elasticsearch client is compatible with currently maintained JS versions.
+
+Language clients are forward compatible; meaning that clients support
+communicating with greater or equal minor versions of Elasticsearch without
+breaking. It does not mean that the client automatically supports new features
+of newer Elasticsearch versions; it is only possible after a release of a new
+client version. For example, a 8.12 client version won't automatically support
+the new features of the 8.13 version of Elasticsearch, the 8.13 client version
+is required for that. Elasticsearch language clients are only backwards
+compatible with default distributions and without guarantees made.

 ## 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>
 ```

 And your `package.json` will look like the following:

+[[redaction]]
+==== Redaction of potentially sensitive data
+
+When the client raises an `Error` that originated at the HTTP layer, like a `ConnectionError` or `TimeoutError`, a `meta` object is often attached to the error object that includes metadata useful for debugging, like request and response information. Because this can include potentially sensitive data, like authentication secrets in an `Authorization` header, the client takes measures to redact common sources of sensitive data when this metadata is attached and serialized.
+
+If your configuration requires extra headers or other configurations that may include sensitive data, you may want to adjust these settings to account for that.
+
+By default, the `redaction` option is set to `{ type: 'replace' }`, which recursively searches for sensitive key names, case insensitive, and replaces their values with the string `[redacted]`.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' },
+})
+
+try {
+  await client.indices.create({ index: 'my_index' })
+} catch (err) {
+  console.log(err.meta.meta.request.options.headers.authorization) // prints "[redacted]"
+}
+----
+
+If you would like to redact additional properties, you can include additional key names to search and replace:
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' },
+  headers: { 'X-My-Secret-Password': 'shhh it's a secret!' },
+  redaction: {
+    type: "replace",
+    additionalKeys: ["x-my-secret-password"]
+  }
+})
+
+try {
+  await client.indices.create({ index: 'my_index' })
+} catch (err) {
+  console.log(err.meta.meta.request.options.headers['X-My-Secret-Password']) // prints "[redacted]"
+}
+----
+
+Alternatively, if you know you're not going to use the metadata at all, setting the redaction type to `remove` will remove all optional sources of potentially sensitive data entirely, or replacing them with `null` for required properties.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' },
+  redaction: { type: "remove" }
+})
+
+try {
+  await client.indices.create({ index: 'my_index' })
+} catch (err) {
+  console.log(err.meta.meta.request.options.headers) // undefined
+}
+----
+
+Finally, if you prefer to turn off redaction altogether, perhaps while debugging on a local developer environment, you can set the redaction type to `off`. This will revert the client to pre-8.11.0 behavior, where basic redaction is only performed during common serialization methods like `console.log` and `JSON.stringify`.
+

+== Getting started
+
+This page guides you through the installation process of the Node.js client,
+shows you how to instantiate the client, and how to perform basic Elasticsearch 
+operations with it.
+
+[discrete]
+=== Requirements
+
+* https://nodejs.org/[Node.js] version 14.x or newer
+* https://docs.npmjs.com/downloading-and-installing-node-js-and-npm[`npm`], usually bundled with Node.js
+
+[discrete]
+=== Installation 
+
+To install the latest version of the client, run the following command:
+
+[source,shell]
+--------------------------
+npm install @elastic/elasticsearch
+--------------------------
+
+Refer to the <<installation>> page to learn more.
+
+
+[discrete]
+=== Connecting
+
+You can connect to the Elastic Cloud using an API key and the Elasticsearch 
+endpoint. 
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://...', // Elasticsearch endpoint
+  auth: {
+    apiKey: { // API key ID and secret
+      id: 'foo',
+      api_key: 'bar',
+    }
+  }
+})
+----
+
+Your Elasticsearch endpoint can be found on the **My deployment** page of your 
+deployment:
+
+image::images/es-endpoint.jpg[alt="Finding Elasticsearch endpoint",align="center"]
+
+You can generate an API key on the **Management** page under Security.
+
+image::images/create-api-key.png[alt="Create API key",align="center"]
+
+For other connection options, refer to the <<client-connecting>> section.
+
+
+[discrete]
+=== Operations
+
+Time to use Elasticsearch! This section walks you through the basic, and most 
+important, operations of Elasticsearch.
+
+
+[discrete]
+==== Creating an index
+
+This is how you create the `my_index` index:
+
+[source,js]
+----
+await client.indices.create({ index: 'my_index' })
+----
+
+
+[discrete]
+==== Indexing documents
+
+This is a simple way of indexing a document:
+
+[source,js]
+----
+await client.index({
+  index: 'my_index',
+  id: 'my_document_id',
+  document: {
+    foo: 'foo',
+    bar: 'bar',
+  },
+})
+----
+
+
+[discrete]
+==== Getting documents
+
+You can get documents by using the following code:
+
+[source,js]
+----
+await client.get({
+  index: 'my_index',
+  id: 'my_document_id',
+})
+----
+
+
+[discrete]
+==== Searching documents
+
+This is how you can create a single match query with the client: 
+
+[source,js]
+----
+await client.search({
+  query: {
+    match: {
+      foo: 'foo'
+    }
+  }
+})
+----
+
+
+[discrete]
+==== Updating documents
+
+This is how you can update a document, for example to add a new field:
+
+[source,js]
+----
+await client.update({
+  index: 'my_index',
+  id: 'my_document_id',
+  doc: {
+    foo: 'bar',
+    new_field: 'new value'
+  }
+})
+----
+
+
+[discrete]
+==== Deleting documents
+
+[source,js]
+----
+await client.delete({
+  index: 'my_index',
+  id: 'my_document_id',
+})
+----
+
+
+[discrete]
+==== Deleting an index
+
+[source,js]
+----
+await client.indices.delete({ index: 'my_index' })
+----
+
+
+[discrete]
+== Further reading
+
+* Use <<client-helpers>> for a more comfortable experience with the APIs.
+* For an elaborate example of how to ingest data into Elastic Cloud, 
+refer to {cloud}/ec-getting-started-node-js.html[this page].
