-## Docs
-
-Documentation can be found on [elastic.co](https://www.elastic.co/guide/en/elasticsearch/client/elasticsearch-js/16.x/index.html).
+Please read the [announcement of the new Elasticsearch JavaScript client](https://www.elastic.co/blog/new-elasticsearch-javascript-client-released) or navigate to the [repository directly](https://github.com/elastic/elasticsearch-js).
 
-## Supported Elasticsearch Versions
+We have built a [migration guide](https://www.elastic.co/guide/en/elasticsearch/client/elasticsearch-js/current/breaking-changes.html) that will help you move to the new client quickly. If you have questions or need help, please [open an issue](https://github.com/elastic/elasticsearch-js/issues/new/choose).
 
-Elasticsearch.js provides support for, and is regularly tested against, Elasticsearch releases 0.90.12 and greater. We also test against the latest changes in several branches in the Elasticsearch repository. To tell the client which version of Elasticsearch you are using, and therefore the API it should provide, set the `apiVersion` config param.
-
-## Examples
-
-Create a client instance
-```js
-var elasticsearch = require('elasticsearch');
-var client = new elasticsearch.Client({
-  host: 'localhost:9200',
-  log: 'trace',
-  apiVersion: '7.2', // use the same version of your Elasticsearch instance
-});
-```
-
-Send a HEAD request to `/` and allow up to 1 second for it to complete.
-```js
-client.ping({
-  // ping usually has a 3000ms timeout
-  requestTimeout: 1000
-}, function (error) {
-  if (error) {
-    console.trace('elasticsearch cluster is down!');
-  } else {
-    console.log('All is well');
-  }
-});
-```
-
-Skip the callback to get a promise back
-```js
-try {
-  const response = await client.search({
-    q: 'pants'
-  });
-  console.log(response.hits.hits)
-} catch (error) {
-  console.trace(error.message)
-}
-```
+---
 
-Find tweets that have "elasticsearch" in their body field
-```js
-const response = await client.search({
-  index: 'twitter',
-  type: 'tweets',
-  body: {
-    query: {
-      match: {
-        body: 'elasticsearch'
-      }
-    }
-  }
-})
+## Documentation
 
-for (const tweet of response.hits.hits) {
-  console.log('tweet:', tweet);
-}
-```
