# Jupyter Integration

Crystal Toolkit offers integration with JupyterLab to allow easy viewing of crystal structures and other Materials Project data interactively.

## Installation

There are two steps to using Crystal Toolkit inside Jupyter:

1. Make sure Jupyter Lab is installed and run using `jupyter lab`, version 3.x. Crystal Toolkit is not supported in the older Jupyter notebooks or older versions of Jupyter Lab.

2. Ensure Crystal Toolkit is installed as normal, `pip install crystal-toolkit --upgrade`

3. Restart Jupyter Lab completely. You be asked to perform a “build,” click OK and it’s normal for this to take a minute. After this it’s ready to use!

The extension may still work on Jupyter Lab 2.x by additionally running:

> `jupyter labextension install crystaltoolkit-extension`

However 2.x is no longer supported, and this command does not need to be run with Jupyter Lab 3.x

## Usage

To use, simply `import crystal_toolkit` and use `pymatgen` as normal for crystal structures to be shown using Crystal Toolkit.
