+# Epsilla
+
+This page covers how to use [Epsilla](https://github.com/epsilla-cloud/vectordb) within LangChain.
+It is broken into two parts: installation and setup, and then references to specific Epsilla wrappers.
+
+## Installation and Setup
+
+- Install the Python SDK with `pip/pip3 install pyepsilla`
+
+## Wrappers
+
+### VectorStore
+
+There exists a wrapper around Epsilla vector databases, allowing you to use it as a vectorstore,
+whether for semantic search or example selection.
+
+To import this vectorstore:
+
+```python
+from langchain.vectorstores import Epsilla
+```
+
+For a more detailed walkthrough of the Epsilla wrapper, see [this notebook](/docs/integrations/vectorstores/epsilla.html)
