 # Roadmap
 
-The project will evolve to support a web-based MDX notebook environment. High level goals:
-
-- Build an interactive notebook system using **Next.js 13** with an App Router.
-- Use **MDX** to author notebook content and render code cells as React components.
-- Provide a **Monaco** based editor for each code cell with live preview.
-- Run user code in a **sandboxed iframe** or Web Worker for security.
-- Integrate **jest-lite** or similar to allow test cells with `describe`, `it`, and `expect`.
-- Store notebooks in **Payload CMS** backed by SQLite by default.
-- Offer CLI commands in `mdxe` to create, edit, and serve notebooks.

-## Blocking Issues
-
-### CI Test Script Missing
-
-The CI checks are failing because there's no `test` script defined in the root package.json, but the CI workflow is trying to run `pnpm test`. This needs to be addressed to allow CI checks to pass for PRs in this repository.
