 ```sh

+For example:

+To run the script for an unreleased snapshot version, append `-SNAPSHOT` to the version name. For example:

-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.

 ### Compatibility
 
-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.
+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 client will verify if it's working with a supported release of Elasticsearch.
+Elastic language clients are guaranteed to be able to communicate with Elasticsearch or Elastic solutions running on the same major version and greater or equal minor version.
+
+Language clients are forward compatible; meaning that clients support communicating with greater minor versions of Elasticsearch. Elastic language clients are not guaranteed to be backwards compatible.

+[discrete]
+===== Add api compatibility header support https://github.com/elastic/elasticsearch-js/pull/1478[#1478]
+
+If you configure the `ELASTIC_CLIENT_APIVERSIONING` to `true` the client will send a compatibility header
+to allow you to use a 7.x client against a 8.x cluster. In this way it will be easier to migrate your code to a newer release of Elasticsearch.

+The most influential optimization is to initialize the client outside of the function, the global scope.
+This practice does not only improve performance but also enables background functionality as – for example – https://www.elastic.co/blog/elasticsearch-sniffing-best-practices-what-when-why-how[sniffing].

+=== Automatic product check
+
+Since v7.14.0, the client performs a required product check before the first call.
+This pre-flight product check allows the client to establish the version of Elasticsearch

+be sent to the server as part of the request pipeline before the main API call is sent.
+In most cases, this will succeed during the very first API call that the client sends.
+Once the product check completes, no further product check HTTP requests are sent for 
+subsequent API calls.

+NOTE: If you are using TypeScript you need to use _snake_case_ style to define 
+the API parameters instead of _camelCase_. 
 
-You can find a partial definition of the request types by importing `RequestParams`, which is used by default in the client and accepts a body (when needed) as a generic to provide a better specification.
+Currently the client exposes two type definitions, the legacy one, which is the default
+and the new one, which will be the default in the next major.
+We strongly recommend to migrate to the new one as soon as possible, as the new types
+are offering a vastly improved developer experience and guarantee you that your code
+will always be in sync with the latest Elasticsearch features.
 
-The body defaults to `RequestBody` and `RequestNDBody`, which are defined as follows:
+[discrete]
+==== New type definitions
+
+The new type definition is more advanced compared to the legacy one. In the legacy
+type definitions you were expected to configure via generics both request and response
+bodies. The new type definitions comes with a complete type definition for every
+Elasticsearch endpoint.
+
+For example:
+
+[source,ts]
+----
+// legacy definitions
+const response = await client.search<SearchResponse<Source>, SearchBody>({
+  index: 'test',
+  body: {
+  query: {

+// new definitions

+  index: 'test',
+  body: {
+  query: {
+      match: { foo: 'bar' }
+    }
+  }
+})
+----
+
+The types are not 100% complete yet. Some APIs are missing (the newest ones, e.g. EQL),
+and others may contain some errors, but we are continuously pushing fixes & improvements.
+
+[discrete]
+==== Request & Response types
+
+Once you migrate to the new types, those are automatically integrated into the Elasticsearch client, you will get them out of the box.
+If everything works, meaning that you won’t get compiler errors, you are good to go!
+The types are already correct, and there is nothing more to do.
+
+If a type is incorrect, you should add a comment `// @ts-expect-error @elastic/elasticsearch`
+telling TypeScript that you are aware of the warning and you would like to temporarily suppress it.
+In this way, your code will compile until the type is fixed, and when it happens, you’ll only need to remove the
+`// @ts-expect-error @elastic/elasticsearch` comment (TypeScript will let you know when it is time).
+Finally, if the type you need is missing, you’ll see that the client method returns (or defines as a parameter)
+a `TODO` type, which accepts any object.
+
+Open an issue in the client repository letting us know if you encounter any problem!
+
+If needed you can import the request and response types.
+
+[source,ts]

+import { Client, estypes } from '@elastic/elasticsearch'
