+
+## Overview
+
+`SpacyNamedEntityExtractor` looks for entities, which are spans in the text. The extractor automatically recognizes and groups them depending on their class, such as people's names, organizations, locations, and other types. The exact classes are determined by the model that you initialize the component with.
+
+`SpacyNamedEntityExtractor` takes a list of documents as input and returns a list of the same documents with their `meta` data enriched with `NamedEntityAnnotations`. A `NamedEntityAnnotation` consists of the type of the entity and the start and end of the span, for example: `NamedEntityAnnotation(entity='PERSON', start=11, end=16, score=None)`.
+
+When the `SpacyNamedEntityExtractor` is initialized, you need to set a `model`. Optionally, you can set `pipeline_kwargs`, which are then passed on to the spaCy pipeline. You can additionally set the `device` that is used to run the component.
+
+## Usage
+
+Install the `spacy-haystack` package to use the `SpacyNamedEntityExtractor`:
+
+```shell
+pip install spacy-haystack
+```
+
+The component works with any [spaCy model](https://spacy.io/models) that contains an NER component.
+
+`SpacyNamedEntityExtractor` accepts a list of `Documents` as its input. The extractor annotates the raw text in the documents and stores the annotations in the document's `meta` dictionary under the `named_entities` key.
+
+```python
+from haystack.dataclasses import Document
+from haystack_integrations.components.extractors.spacy import (
+    SpacyNamedEntityExtractor,
+)
+
+extractor = SpacyNamedEntityExtractor(model="en_core_web_sm")
+
+documents = [
+    Document(content="My name is Clara and I live in Berkeley, California."),
+    Document(content="I'm Merlin, the happy pig!"),
+    Document(content="New York State is home to the Empire State Building."),
+]
+
+result = extractor.run(documents)
+print(result["documents"])
+```
+
+Here is the example result:
+
+```python
+[Document(id=aec840d1b6c85609f4f16c3e222a5a25fd8c4c53bd981a40c1268ab9c72cee10, content: 'My name is Clara and I live in Berkeley, California.', meta: {'named_entities': [NamedEntityAnnotation(entity='PERSON', start=11, end=16, score=None), NamedEntityAnnotation(entity='GPE', start=31, end=39, score=None), NamedEntityAnnotation(entity='GPE', start=41, end=51, score=None)]}),
+Document(id=98f1dc5d0ccd9d9950cd191d1076db0f7af40c401dd7608f11c90cb3fc38c0c2, content: 'I'm Merlin, the happy pig!', meta: {'named_entities': [NamedEntityAnnotation(entity='PERSON', start=4, end=10, score=None)]}),

+```
+
+### Get stored annotations
+
+This component includes the `get_stored_annotations` helper class method that allows you to retrieve the annotations stored in a `Document` transparently:
+
+```python
+from haystack.dataclasses import Document
+from haystack_integrations.components.extractors.spacy import (
+    SpacyNamedEntityExtractor,
+)
+
+extractor = SpacyNamedEntityExtractor(model="en_core_web_sm")
+
+documents = [
+    Document(content="My name is Clara and I live in Berkeley, California."),
+    Document(content="I'm Merlin, the happy pig!"),
+    Document(content="New York State is home to the Empire State Building."),
+]
+
+result = extractor.run(documents)
+
+annotations = [
+    SpacyNamedEntityExtractor.get_stored_annotations(doc) for doc in result["documents"]
+]
+print(annotations)
+
+# If a Document doesn't contain any annotations, this returns None.
+new_doc = Document(content="In one of many possible worlds...")
+assert SpacyNamedEntityExtractor.get_stored_annotations(new_doc) is None
