# Chroma

This page covers how to use the Chroma ecosystem within LangChain. It is broken into two parts: installation and setup, and then references to specific Chroma wrappers.

## Installation and Setup

- Install the Python package with `pip install chromadb`

## Wrappers

### VectorStore

There exists a wrapper around Chroma vector databases, allowing you to use it as a vectorstore, whether for semantic search or example selection.

To import this vectorstore:

    from langchain.vectorstores import Chroma

For a more detailed walkthrough of the Chroma wrapper, see this notebook
