## Description

# Jupyter Core

[![Build Status](https://github.com/jupyter/jupyter_core/actions/workflows/test.yml/badge.svg?query=branch%3Amain++)](https://github.com/jupyter/jupyter_core/actions/workflows/test.yml/badge.svg?query=branch%3Amain++)
[![Documentation Status](https://readthedocs.org/projects/jupyter-core/badge/?version=latest)](http://jupyter-core.readthedocs.io/en/latest/?badge=latest)

Core common functionality of Jupyter projects.

This package contains base application classes and configuration inherited by other projects.
It doesn't do much on its own.

# Development Setup

The [Jupyter Contributor Guides](https://docs.jupyter.org/en/latest/contributing/content-contributor.html) provide extensive information on contributing code or documentation to Jupyter projects. The limited instructions below for setting up a development environment are for your convenience.

## Coding

You'll need Python and `pip` on the search path. Clone the Jupyter Core git repository to your computer, for example in `/my/projects/jupyter_core`.
Now create an [editable install](https://pip.pypa.io/en/stable/reference/pip_install/#editable-installs)
and download the dependencies of code and test...

## AI interpretation — verify before relying

Jupyter Core provides base application classes and configuration infrastructure that other Jupyter projects inherit from, handling core common functionality without standalone features.

Verdict: Jupyter Core is a stable, actively maintained foundation package with no known vulnerabilities, permissive licensing, and minimal dependencies. It is suitable for projects that need Jupyter infrastructure but should not be installed directly unless your application explicitly requires its base classes or configuration utilities.
