+# Change notes
+
+## My prediction
+I updated the README to add a project description.
+
+## Claude's summary of what changed
+- `README.md`: Added a new **"About this project"** section describing the app as a minimal Node.js command-line notes manager, explaining that it stores plain-text notes in a local JSON file, exposes `add`/`list`/`delete` commands, and is intentionally small — split into `notes.js` (entry point) and a `lib/` folder (storage + config) — to make it easy to practice Git workflows.
+
+Nothing looked unintended: the change was the additive README section, now merged to `main`. No stray edits in other files.
