 also not be done, that can be done when the pull request is [integrated

-# What is it?
+Where possible the package uses existing Python APIs and data structures to make it easy to switch between numpy,
+pandas, or scikit-learn to their Elasticsearch powered equivalents. In general, the data resides in Elasticsearch and
+not in memory, which allows Eland to access large datasets stored in Elasticsearch.
 
-eland is a Elasticsearch client Python package to analyse, explore and manipulate data that resides in Elasticsearch. 
+Eland also provides tools to upload trained machine learning models from common libraries like
-Where possible the package uses existing Python APIs and data structures to make it easy to switch between numpy, 
+[scikit-learn](https://scikit-learn.org), [XGBoost](https://xgboost.readthedocs.io),  and
-pandas, scikit-learn to their Elasticsearch powered equivalents. In general, the data resides in Elasticsearch and 
+[LightGBM](https://lightgbm.readthedocs.io) into Elasticsearch.
-not in memory, which allows eland to access large datasets stored in Elasticsearch.
 
-For example, to explore data in a large Elasticsearch index, simply create an eland DataFrame from an Elasticsearch 
+## Getting Started
-index pattern, and explore using an API that mirrors a subset of the pandas.DataFrame API: 
 
+Eland can be installed from [PyPI](https://pypi.org/project/eland) with Pip:
+
+```bash
+$ python -m pip install eland
 ```
+
+If using Eland to upload NLP models to Elasticsearch install the PyTorch extras:
+```bash
+$ python -m pip install 'eland[pytorch]'
+```
+
+Eland can also be installed from [Conda Forge](https://anaconda.org/conda-forge/eland) with Conda:
+
+```bash
+$ conda install -c conda-forge eland
+```
+
+### Compatibility
+
+- Supports Python 3.9, 3.10, 3.11 and 3.12.
+- Supports Pandas 1.5 and 2.
+- Supports Elasticsearch 8+ clusters, recommended 8.16 or later for all features to work.
+  If you are using the NLP with PyTorch feature make sure your Eland minor version matches the minor 
+  version of your Elasticsearch cluster. For all other features it is sufficient for the major versions
+  to match.
+- You need to install the appropriate version of PyTorch to import an NLP model. Run `python -m pip
+  install 'eland[pytorch]'` to install that version.
+  
+
+### Prerequisites
+
+Users installing Eland on Debian-based distributions may need to install prerequisite packages for the transitive
+dependencies of Eland:
+
+```bash
+$ sudo apt-get install -y \
+  build-essential pkg-config cmake \
+  python3-dev libzip-dev libjpeg-dev
+```
+
+Note that other distributions such as CentOS, RedHat, Arch, etc. may require using a different package manager and
+specifying different package names. 
+
+### Docker
+
+If you want to use Eland without installing it just to run the available scripts, use the Docker
+image.
+It can be used interactively:
+
+```bash
+$ docker run -it --rm --network host docker.elastic.co/eland/eland
+```
+
+Running installed scripts is also possible without an interactive shell, e.g.:
+
+```bash
+$ docker run -it --rm --network host \
+    docker.elastic.co/eland/eland \
+    eland_import_hub_model \
+      --url http://host.docker.internal:9200/ \
+      --hub-model-id elastic/distilbert-base-cased-finetuned-conll03-english \
+      --task-type ner
+```
+
+### Connecting to Elasticsearch 
+
+Eland uses the [Elasticsearch low level client](https://elasticsearch-py.readthedocs.io) to connect to Elasticsearch. 
+This client supports a range of [connection options and authentication options](https://elasticsearch-py.readthedocs.io/en/stable/api.html#elasticsearch). 
+
+You can pass either an instance of `elasticsearch.Elasticsearch` to Eland APIs
+or a string containing the host to connect to:
+
+```python
+import eland as ed
+
+# Connecting to an Elasticsearch instance running on 'http://localhost:9200'
+df = ed.DataFrame("http://localhost:9200", es_index_pattern="flights")
+
+# Connecting to an Elastic Cloud instance
+from elasticsearch import Elasticsearch
+
+es = Elasticsearch(
+    cloud_id="cluster-name:...",
+    basic_auth=("elastic", "<password>")
+)
+df = ed.DataFrame(es, es_index_pattern="flights")
+```
+
+## DataFrames in Eland
+
+`eland.DataFrame` wraps an Elasticsearch index in a Pandas-like API
+and defers all processing and filtering of data to Elasticsearch
+instead of your local machine. This means you can process large
+amounts of data within Elasticsearch from a Jupyter Notebook
+without overloading your machine.

->>> df = ed.read_es('http://localhost:9200', 'reviews') 
+>>> # Connect to 'flights' index via localhost Elasticsearch node
+>>> df = ed.DataFrame('http://localhost:9200', 'flights')

-## Development Setup
+### NLP with PyTorch
 
-1. Create a virtual environment in Python 
+For NLP tasks, Eland allows importing PyTorch trained BERT models into Elasticsearch. Models can be either plain PyTorch
+models, or supported [transformers](https://huggingface.co/transformers) models from the
+[Hugging Face model hub](https://huggingface.co/models).
 
-For example, 
+```bash
-
+$ eland_import_hub_model \
-```
+  --url http://localhost:9200/ \
-python3 -m venv env
+  --hub-model-id elastic/distilbert-base-cased-finetuned-conll03-english \
+  --task-type ner \
+  --start
 ```
 
-2. Activate the virtual environment
+The example above will automatically start a model deployment. This is a
+good shortcut for initial experimentation, but for anything that needs
+good throughput you should omit the `--start` argument from the Eland
+command line and instead start the model using the ML UI in Kibana.
+The `--start` argument will deploy the model with one allocation and one
+thread per allocation, which will not offer good performance. When starting
+the model deployment using the ML UI in Kibana or the Elasticsearch
+[API](https://www.elastic.co/guide/en/elasticsearch/reference/current/start-trained-model-deployment.html)
+you will be able to set the threading options to make the best use of your
+hardware.

-## Versions and Compatibility
-
-### Python Version Support
-
-Officially Python 3.5.3 and above, 3.6, 3.7, and 3.8.
-
-eland depends on pandas version 0.25.3. 
-
-#### Elasticsearch Versions
-
-eland is versioned like the Elastic stack (eland 7.5.1 is compatible with Elasticsearch 7.x up to 7.5.1)
-
-A major version of the client is compatible with the same major version of Elasticsearch. 
-
-No compatibility assurances are given between different major versions of the client and Elasticsearch. 
-Major differences likely exist between major versions of Elasticsearch, 
-particularly around request and response object formats, but also around API urls and behaviour.
-
-## Connecting to Elasticsearch Cloud
-

+# Data Frames [dataframes]
+
+`eland.DataFrame` wraps an Elasticsearch index in a Pandas-like API and defers all processing and filtering of data to Elasticsearch instead of your local machine. This means you can process large amounts of data within Elasticsearch from a Jupyter Notebook without overloading your machine.
+
+```python
+>>> import eland as ed
+>>>
+# Connect to 'flights' index via localhost Elasticsearch node
+>>> df = ed.DataFrame('http://localhost:9200', 'flights')
+
+# eland.DataFrame instance has the same API as pandas.DataFrame
+# except all data is in Elasticsearch. See .info() memory usage.

+---
+
+# Eland Python client [overview]
+
+Eland is a Python client and toolkit for DataFrames and {{ml}} in {{es}}. Full documentation is available on [Read the Docs](https://eland.readthedocs.io). Source code is available on [GitHub](https://github.com/elastic/eland).
+
+
+## Compatibility [_compatibility]
+
+* Supports Python 3.9+ and Pandas 1.5
+* Supports {{es}} 8+ clusters, recommended 8.16 or later for all features to work. Make sure your Eland major version matches the major version of your Elasticsearch cluster.
+
+The recommended way to set your requirements in your `setup.py` or `requirements.txt` is::
+
+```
+# Elasticsearch 8.x
+eland>=8,<9
+```
+```
+# Elasticsearch 7.x
+eland>=7,<8
+```
+
+## Getting Started [_getting_started]
+
+Create a `DataFrame` object connected to an {{es}} cluster running on `http://localhost:9200`:
+
+```python
+>>> import eland as ed
+>>> df = ed.DataFrame(
+...    es_client="http://localhost:9200",
+...    es_index_pattern="flights",
+... )
+>>> df
+       AvgTicketPrice  Cancelled  ... dayOfWeek           timestamp
+0          841.265642      False  ...         0 2018-01-01 00:00:00
+1          882.982662      False  ...         0 2018-01-01 18:27:00
+2          190.636904      False  ...         0 2018-01-01 17:11:14

+
+[13059 rows x 27 columns]
+```
+
+
+### Elastic Cloud [_elastic_cloud]
+
+You can also connect Eland to an Elasticsearch instance in Elastic Cloud:
+
+```python
+>>> import eland as ed
+>>> from elasticsearch import Elasticsearch
+
+# First instantiate an 'Elasticsearch' instance connected to Elastic Cloud
+>>> es = Elasticsearch(cloud_id="...", api_key="...")
+
+# then wrap the client in an Eland DataFrame:
+>>> df = ed.DataFrame(es, es_index_pattern="flights")
+>>> df.head(5)
+       AvgTicketPrice  Cancelled  ... dayOfWeek           timestamp
+0          841.265642      False  ...         0 2018-01-01 00:00:00
+1          882.982662      False  ...         0 2018-01-01 18:27:00
+2          190.636904      False  ...         0 2018-01-01 17:11:14
+3          181.694216       True  ...         0 2018-01-01 10:33:28
+4          730.041778      False  ...         0 2018-01-01 05:13:00
+[5 rows x 27 columns]
+```
+
+Eland can be used for complex queries and aggregations:
+
+```python
+>>> df[df.Carrier != "Kibana Airlines"].groupby("Carrier").mean(numeric_only=False)
+                  AvgTicketPrice  Cancelled                     timestamp

+# Machine Learning [machine-learning]
+
+
+## Trained models [ml-trained-models]
+
+Eland allows transforming *some* 
+[trained models](https://eland.readthedocs.io/en/latest/reference/api/eland.ml.MLModel.import_model.html#parameters) from scikit-learn, XGBoost, 
+and LightGBM libraries to be serialized and used as an inference model in {{es}}.
+
+```python
+>>> from xgboost import XGBClassifier
+>>> from eland.ml import MLModel
+
+# Train and exercise an XGBoost ML model locally
+>>> xgb_model = XGBClassifier(booster="gbtree")
+>>> xgb_model.fit(training_data[0], training_data[1])
+
+>>> xgb_model.predict(training_data[0])
+[0 1 1 0 1 0 0 0 1 0]
+
+# Import the model into Elasticsearch
+>>> es_model = MLModel.import_model(
+    es_client="http://localhost:9200",
+    model_id="xgb-classifier",
+    model=xgb_model,
+    feature_names=["f0", "f1", "f2", "f3", "f4"],
+)
+
+# Exercise the ML model in Elasticsearch with the training data
+>>> es_model.predict(training_data[0])
+[0 1 1 0 1 0 0 0 1 0]
+```
+
+
+## Natural language processing (NLP) with PyTorch [ml-nlp-pytorch]
+
+::::{important}
+You need to install the appropriate version of PyTorch to import an NLP model. Run `python -m pip install 'eland[pytorch]'` to install that version.
+::::
+
+
+For NLP tasks, Eland enables you to import PyTorch models into {{es}}. Use the `eland_import_hub_model` script to download and install supported [transformer models](https://huggingface.co/transformers) from the [Hugging Face model hub](https://huggingface.co/models). For example:
+
+```bash
+eland_import_hub_model <authentication> \ <1>
+  --url http://localhost:9200/ \ <2>
+  --hub-model-id elastic/distilbert-base-cased-finetuned-conll03-english \ <3>
+  --task-type ner \ <4>
+  --start
+```
+ 
+1. Use an authentication method to access your cluster. Refer to [Authentication methods](machine-learning.md#ml-nlp-pytorch-auth).
+2. The cluster URL. Alternatively, use `--cloud-id`.
+3. Specify the identifier for the model in the Hugging Face model hub.
+4. Specify the type of NLP task. Supported values are `fill_mask`, `ner`, `question_answering`, `text_classification`, `text_embedding`, `text_expansion`, `text_similarity` and `zero_shot_classification`.
+
+
+For more information about the available options, run `eland_import_hub_model` with the `--help` option.
+
+```bash
+eland_import_hub_model --help
+```
+
+
+### Import model with Docker [ml-nlp-pytorch-docker]
+
+::::{important}
+To use the Docker container, you need to clone the Eland repository: [https://github.com/elastic/eland](https://github.com/elastic/eland)
+::::
+
+
+If you want to use Eland without installing it, you can use the Docker image:
+
+You can use the container interactively:
+
+```bash
+docker run -it --rm --network host docker.elastic.co/eland/eland
+```
+
+Running installed scripts is also possible without an interactive shell, for example:
+
+```bash
+docker run -it --rm docker.elastic.co/eland/eland \
+    eland_import_hub_model \
+      --url $ELASTICSEARCH_URL \
+      --hub-model-id elastic/distilbert-base-uncased-finetuned-conll03-english \
+      --start
+```
+
+Replace the `$ELASTICSEARCH_URL` with the URL for your Elasticsearch cluster. For authentication purposes, include an administrator username and password in the URL in the following format: `https://username:password@host:port`.
+
+
+### Install models in an air-gapped environment [ml-nlp-pytorch-air-gapped]
+
+You can install models in a restricted or closed network by pointing the `eland_import_hub_model` script to local files.
+
+For an offline install of a Hugging Face model, the model first needs to be cloned locally, Git and [Git Large File Storage](https://git-lfs.com/) are required to be installed in your system.
+
+1. Select a model you want to use from Hugging Face. Refer to the [compatible third party model](docs-content://explore-analyze/machine-learning/nlp/ml-nlp-model-ref.md) list for more information on the supported architectures.
+2. Clone the selected model from Hugging Face by using the model URL. For example:
+
+    ```bash
+    git clone https://huggingface.co/dslim/bert-base-NER
+    ```
+
+    This command results in a local copy of of the model in the directory `bert-base-NER`.
+
+3. Use the `eland_import_hub_model` script with the `--hub-model-id` set to the directory of the cloned model to install it:
+
+    ```bash
+    eland_import_hub_model \
+          --url 'XXXX' \
+          --hub-model-id /PATH/TO/MODEL \
+          --task-type ner \
+          --es-username elastic --es-password XXX \
+          --es-model-id bert-base-ner
+    ```
+
+    If you use the Docker image to run `eland_import_hub_model` you must bind mount the model directory, so the container can read the files:
+
+    ```bash
+    docker run --mount type=bind,source=/PATH/TO/MODEL,destination=/model,readonly -it --rm docker.elastic.co/eland/eland \
+        eland_import_hub_model \
+          --url 'XXXX' \
+          --hub-model-id /model \
+          --task-type ner \
+          --es-username elastic --es-password XXX \
+          --es-model-id bert-base-ner
+    ```
+
+    Once it’s uploaded to {{es}}, the model will have the ID specified by `--es-model-id`. If it is not set, the model ID is derived from `--hub-model-id`; spaces and path delimiters are converted to double underscores `__`.
+
+
+
+### Connect to Elasticsearch through a proxy [ml-nlp-pytorch-proxy]
+
+Behind the scenes, Eland uses the `requests` Python library, which [allows configuring proxies through an environment variable](https://requests.readthedocs.io/en/latest/user/advanced/#proxies). For example, to use an HTTP proxy to connect to an HTTPS Elasticsearch cluster, you need to set the `HTTPS_PROXY` environment variable when invoking Eland:
+
+```bash
+HTTPS_PROXY=http://proxy-host:proxy-port eland_import_hub_model ...
+```
+
+If you disabled security on your Elasticsearch cluster, you should use `HTTP_PROXY` instead.
+
+
+### Authentication methods [ml-nlp-pytorch-auth]
+
+The following authentication options are available when using the import script:
+
+* Elasticsearch username and password authentication (specified with the `-u` and `-p` options):
+
+    ```bash
+    eland_import_hub_model -u <username> -p <password> --cloud-id <cloud-id> ...
+    ```
+
+    These `-u` and `-p` options also work when you use `--url`.
+
+* Elasticsearch username and password authentication (embedded in the URL):
+
+    ```bash
+    eland_import_hub_model --url https://<user>:<password>@<hostname>:<port> ...
+    ```
+
+* Elasticsearch API key authentication:
+
+    ```bash
+    eland_import_hub_model --es-api-key <api-key> --url https://<hostname>:<port> ...
+    ```
+
+* HuggingFace Hub access token (for private models):
+
+    ```bash
+    eland_import_hub_model --hub-access-token <access-token> ...
+    ```
+
+
+
+### TLS/SSL [ml-nlp-pytorch-tls]
+
+The following TLS/SSL options for Elasticsearch are available when using the import script:
+
+* Specify alternate CA bundle to verify the cluster certificate:
+
+    ```bash
+    eland_import_hub_model --ca-certs CA_CERTS ...
+    ```
+
+* Disable TLS/SSL verification altogether (strongly discouraged):
+
+    ```bash
+    eland_import_hub_model --insecure ...
+    ```
+
+

-:mod:`eland` is an open source, Apache2-licensed elasticsearch Python client to analyse, explore and manipulate data that resides in elasticsearch.
-Where possible the package uses existing Python APIs and data structures to make it easy to switch between Numpy, Pandas, Scikit-learn to their elasticsearch powered equivalents.
-In general, the data resides in elasticsearch and not in memory, which allows eland to access large datasets stored in elasticsearch.
