+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 --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
+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!)*.

-### Node.js support
-
-NOTE: The minimum supported version of Node.js is `v12`.
-
-The client versioning follows the Elastc Stack versioning, this means that
-major, minor, and patch releases are done following a precise schedule that
-often does not coincide with the [Node.js release](https://nodejs.org/en/about/releases/) times.
-
-To avoid support insecure and unsupported versions of Node.js, the
-client **will drop the support of EOL versions of Node.js between minor releases**.
-Typically, as soon as a Node.js version goes into EOL, the client will continue
-to support that version for at least another minor release. If you are using the client
-with a version of Node.js that will be unsupported soon, you will see a warning
-in your logs (the client will start logging the warning with two minors in advance).
-
-Unless you are **always** using a supported version of Node.js, 
-we recommend defining the client dependency in your
-`package.json` with the `~` instead of `^`. In this way, you will lock the
-dependency on the minor release and not the major. (for example, `~7.10.0` instead
-of `^7.10.0`).
-
-| Node.js Version | Node.js EOL date | End of support         |
-| --------------- |------------------| ---------------------- |
-| `8.x`           | `December 2019`  | `7.11` (early 2021)    |
-| `10.x`          | `April 2021`      | `7.12` (mid 2021)     |
-
 ### 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 minimum supported version of Node.js is `v8`.
+
+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.

+   * @param {list} index - A comma-separated list of index names to search; use `_all` or empty string to perform the operation on all indices
+   * @param {list} type - A comma-separated list of document types to search; leave empty to perform the operation on all types
+   * @param {string} analyzer - The analyzer to use for the query string
+   * @param {boolean} analyze_wildcard - Specify whether wildcard and prefix queries should be analyzed (default: false)
+   * @param {enum} default_operator - The default operator for query string query (AND or OR)
+   * @param {string} df - The field to use as default where no field prefix is given in the query string
+   * @param {number} from - Starting offset (default: 0)
+   * @param {boolean} ignore_unavailable - Whether specified concrete indices should be ignored when unavailable (missing or closed)
+   * @param {boolean} allow_no_indices - Whether to ignore if a wildcard indices expression resolves into no concrete indices. (This includes `_all` string or when no indices have been specified)
+   * @param {enum} conflicts - What to do when the delete by query hits version conflicts?
+   * @param {enum} expand_wildcards - Whether to expand wildcard expression to concrete indices that are open, closed or both.
+   * @param {boolean} lenient - Specify whether format-based query failures (such as providing text to a numeric field) should be ignored
+   * @param {string} preference - Specify the node or shard the operation should be performed on (default: random)
+   * @param {string} q - Query in the Lucene query string syntax
+   * @param {list} routing - A comma-separated list of specific routing values
+   * @param {time} scroll - Specify how long a consistent view of the index should be maintained for scrolled search
+   * @param {enum} search_type - Search operation type
+   * @param {time} search_timeout - Explicit timeout for each search request. Defaults to no timeout.
+   * @param {number} size - Number of hits to return (default: 10)
+   * @param {list} sort - A comma-separated list of <field>:<direction> pairs
+   * @param {list} _source - True or false to return the _source field or not, or a list of fields to return
+   * @param {list} _source_excludes - A list of fields to exclude from the returned _source field
+   * @param {list} _source_includes - A list of fields to extract and return from the _source field
+   * @param {number} terminate_after - The maximum number of documents to collect for each shard, upon reaching which the query execution will terminate early.
+   * @param {list} stats - Specific 'tag' of the request for logging and statistical purposes
+   * @param {boolean} version - Specify whether to return document version as part of a hit
+   * @param {boolean} request_cache - Specify if request cache should be used for this request or not, defaults to index level setting
+   * @param {boolean} refresh - Should the effected indexes be refreshed?
+   * @param {time} timeout - Time each individual bulk request should wait for shards that are unavailable.
+   * @param {string} wait_for_active_shards - Sets the number of shard copies that must be active before proceeding with the delete by query operation. Defaults to 1, meaning the primary shard only. Set to `all` for all shard copies, otherwise set to any non-negative value less than or equal to the total number of copies for the shard (number of replicas + 1)
+   * @param {number} scroll_size - Size on the scroll request powering the delete by query
+   * @param {boolean} wait_for_completion - Should the request should block until the delete by query is complete.
+   * @param {number} requests_per_second - The throttle for this request in sub-requests per second. -1 means no throttle.
+   * @param {number} slices - The number of slices this task should be divided into. Defaults to 1 meaning the task isn't sliced into subtasks.
