+Integration with LangChain, LlamaIndex, and frameworks.
+
+## LangChain

+```python
+from langchain_chroma import Chroma
+from langchain_openai import OpenAIEmbeddings
+
+vectorstore = Chroma.from_documents(
+    documents=docs,
+    embedding=OpenAIEmbeddings(),
+    persist_directory="./chroma_db"
+)
+
+# Query
+results = vectorstore.similarity_search("query", k=3)
+
+# As retriever
+retriever = vectorstore.as_retriever()
+```
+
+## LlamaIndex
+
+```python
+from llama_index.vector_stores.chroma import ChromaVectorStore
+import chromadb
+
+db = chromadb.PersistentClient(path="./chroma_db")
+collection = db.get_or_create_collection("docs")
