## What it is
Hydrogen is an Atom editor plugin that brings Jupyter kernel-based interactive coding to any text file, letting users run code line-by-line or by cells with inline results, plots, and rich media. It supports any Jupyter kernel (Python, R, Julia, JavaScript, and more), remote kernel gateways, and notebook import/export.

## Use cases
- run python code interactively inside my editor
- execute code line by line and see inline results
- plot matplotlib charts inline while coding
- connect to a remote jupyter kernel gateway
- convert a script file to a jupyter notebook
- inspect variables and get completions from a running kernel
- run R snippets interactively in atom

## When to choose
- you already use Atom locally and want Jupyter-style interactive execution in plain text files
- you need to export or import .ipynb notebooks from a text editor
- you want kernel-agnostic interactive coding across many languages

## When to avoid
- you are starting fresh - Atom is sunset and new packages cannot be published; use VS Code's Jupyter integration, PyCharm, or nteract instead
- you need a full notebook UI with cell results saved in the file
- you rely on active maintenance or community support
