+## Installation
+Use `pip` to install OpenSearch:
+
+```console
+pip install opensearch-haystack
+```
+## Usage
+Once installed, initialize your OpenSearch database to use it with Haystack 2.0:
+
+```python
+from opensearch_haystack import OpenSearchDocumentStore
+
+document_store = OpenSearchDocumentStore()
+```
+
+### Writing Documents to OpenSearchDocumentStore
+To write documents to `OpenSearchDocumentStore`, create an indexing pipeline.
+
+```python
+from haystack.components.file_converters import TextFileToDocument
+from haystack.components.writers import DocumentWriter
+
+indexing = Pipeline()
+indexing.add_component("converter", TextFileToDocument())
+indexing.add_component("writer", DocumentWriter(document_store))
+indexing.connect("converter", "writer")
+indexing.run({"converter": {"paths": file_paths}})
+```
