**Summary** Hydrogen is an Atom package that lets developers run code inline within the editor by connecting to any installed Jupyter kernel, providing instant feedback, rich media (plots, images, video), autocompletion, watch expressions, and kernel management. It’s aimed at data‑science, scientific‑computing, and interactive‑coding workflows—especially users who want Light‑Table‑style immediacy inside a customizable text editor.
