 ### Compatibility
 
-Language clients are forward compatible; meaning that clients support communicating with greater or equal minor versions of Elasticsearch.
-Elasticsearch language clients are only backwards compatible with default distributions and without guarantees made.
+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.

 ## 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
+}

 If you need to customize the client behavior heavily, you are in the right
