 ### Code generation

-If you want to run the code generation you should run the following command:
+The contents of the API folder and the `docs/reference.asciidoc` file are generated by a script.<br/>
+To run the script, use the following command:
+
 ```sh
-node scripts/generate --tag <tag name>
-# or
-node scripts/generate --branch <branch name>
+node scripts/generate --version <version name>
+```
+
+For example:
+
+```sh
+node scripts/generate --version 7.15.0
+```
+
+To run the script for an unreleased snapshot version, append `-SNAPSHOT` to the version name. For example:
+
+```sh
+node scripts/generate --version 8.0.0-SNAPSHOT
 ```
-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 Node.js client can be configured to emit an HTTP header

+which signals to Elasticsearch that the client is requesting
+``7.x`` version of request and response bodies. This allows for
+upgrading from 7.x to 8.x version of Elasticsearch without upgrading
+everything at once. Elasticsearch should be upgraded first after
+the compatibility header is configured and clients should be upgraded
+second.
+To enable to setting, configure the environment variable

+=== Automatic product check
+
+Since v7.14.0, the client performs a required product check before the first call.

+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.

+subsequent API calls.
