# Jina

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

## Installation and Setup
- Install the Python SDK with `pip install jina`
- Get a Jina AI Cloud auth token from [here](https://cloud.jina.ai/settings/tokens) and set it as an environment variable (`JINA_AUTH_TOKEN`)

## Wrappers

### Embeddings

There exists a Jina Embeddings wrapper, which you can access with 
```python
from langchain.embeddings import JinaEmbeddings
```
For a more detailed walkthrough of this, see [this notebook](../modules/models/text_embedding/examples/jina.ipynb)
