+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+
+      (b) You must cause any modified files to carry prominent notices

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# Astra Store
+
+## Installation
+install astra-haystack package locally to run integration tests:
+
+Open in gitpod:
+[![Open in Gitpod](https://gitpod.io/button/open-in-gitpod.svg)](https://gitpod.io/#https://github.com/Anant/astra-haystack/tree/main)
+
+Switch Python version to 3.9 (Requires 3.8+ but not 3.12)
+```
+pyenv install 3.9
+pyenv local 3.9
+```
+
+Local install for the package
+`pip install -e .`
+To execute integration tests, add needed environment variables
+`ASTRA_DB_ID=<id>`
+`ASTRA_DB_APPLICATION_TOKEN=<token>`
+and execute
+`python examples/example.py`
+
+Install requirements
+`pip install -r requirements.txt`
+
+Export environment variables
+```
+export KEYSPACE_NAME=
+export COLLECTION_NAME=
+export OPENAI_API_KEY=
+export ASTRA_DB_ID=
+export ASTRA_DB_REGION=
+export ASTRA_DB_APPLICATION_TOKEN=
+```
+
+run the python examples
+`python example/example.py`
+or
+`python example/pipeline_example.py`
+
+## Usage
+
+This package includes Astra Document Store and Astra Retriever classes that integrate with Haystack, allowing you to easily perform document retrieval or RAG with Astra, and include those functions in Haystack pipelines.
+
+### In order to use the Document Store directly:
+
+Import the Document Store:
+```
+from astra_store.document_store import AstraDocumentStore
+from haystack.preview.document_stores import DuplicatePolicy
+```
+
+Load in environment variables:
+```
+astra_id = os.getenv("ASTRA_DB_ID", "")
+astra_region = os.getenv("ASTRA_DB_REGION", "us-east1")
+
+astra_application_token = os.getenv("ASTRA_DB_APPLICATION_TOKEN", "")
+collection_name = os.getenv("COLLECTION_NAME", "haystack_vector_search")
+keyspace_name = os.getenv("KEYSPACE_NAME", "recommender_demo")
+```
+
+Create the Document Store object:
+```
+document_store = AstraDocumentStore(
+    astra_id=astra_id,
+    astra_region=astra_region,
+    astra_collection=collection_name,
+    astra_keyspace=keyspace_name,
+    astra_application_token=astra_application_token,
+    duplicates_policy=DuplicatePolicy.SKIP,
+    embedding_dim=384,
+)
+```
+
+Then you can use the document store functions like count_document below:
+`document_store.count_documents()`
+
+### Using the Astra Retriever with Haystack Pipelines
+
+Create the Document Store object like above, then import and create the Pipeline:
+
+```
+from haystack.preview import Pipeline
+pipeline = Pipeline()
+```
+
+Add your AstraRetriever into the pipeline
+`pipeline.add_component(instance=AstraSingleRetriever(document_store=document_store), name="retriever")`
+
+Add other components and connect them as desired. Then run your pipeline:
+`pipeline.run(...)`
