## What it is
EIN is an Emacs Lisp package providing a Jupyter notebook client and integrated REPL inside GNU Emacs, supporting code evaluation, completion, and kernel connection across languages. The project has been sunset since 2023, with a successor greenfield implementation at commercial-emacs/xjupyter.

## Use cases
- edit jupyter notebooks in emacs
- run ipython cells from emacs buffers
- connect a jupyter kernel to a python buffer
- open and evaluate .ipynb files in emacs
- use a slime-like REPL for python in emacs
- connect to a remote jupyter server over ssh

## When to choose
- you live in Emacs and want notebook editing without leaving it
- you need kernel-connected evaluation and completion in arbitrary Emacs buffers
- you want org-mode integration via ob-ein

## When to avoid
- you are on non-WSL Windows
- you need full parity with Jupyter's web-first features like rich inline widgets
- you need robust undo in notebooks - the successor xjupyter is recommended instead
