 # Neo4j GenAI package for Python
 
 This repository contains the official Neo4j GenAI features for Python.
+
+## Installation
+
+This package requires Python (>=3.8.1).
+
+To install the latest stable version, use:
+
+```shell
+pip install neo4j-genai
+```
+
+## Example
+After setting up a Neo4j database instance:
+```python
+from neo4j import GraphDatabase
+from neo4j_genai import VectorRetriever
+
+from random import random
+
+from neo4j_genai.indexes import create_vector_index
+
+URI = "neo4j://localhost:7687"
+AUTH = ("neo4j", "password")
+
+INDEX_NAME = "embedding-name"
+DIMENSION = 1536
+
+# Connect to Neo4j database
+driver = GraphDatabase.driver(URI, auth=AUTH)
+
+# Creating the index
+create_vector_index(
+    driver,
+    INDEX_NAME,
+    label="Document",
+    property="propertyKey",
+    dimensions=DIMENSION,
+    similarity_fn="euclidean",
+)
+
+# Initialize the retriever
+retriever = VectorRetriever(driver, INDEX_NAME)
+
+# Upsert the vector
+vector = [random() for _ in range(DIMENSION)]
+insert_query = (
+    "MERGE (n:Document)"
+    "WITH n "
+    "CALL db.create.setNodeVectorProperty(n, 'propertyKey', $vector)"
+    "RETURN n"
+)
+parameters = {
+    "vector": vector,
+}
+
+driver.execute_query(insert_query, parameters)
+
+# Perform the similarity search for a vector query
+query_vector = [random() for _ in range(DIMENSION)]
+print(retriever.search(query_vector=query_vector, top_k=5))
+
+```
