+# Demo app — `tasks`
+
+A deliberately tiny command-line task tracker. It exists to be *changed by an AI*, so it's small
+enough to read in a minute but real enough to have more than one file — which is exactly where the
+copy-paste workflow starts to hurt.
+
+This is the running example for **Module 1** (where you feel the copy-paste problem) and **Module 2**
+(where you put it under version control).
+
+## Files
+
+- `tasks.py` — the core logic (`Task`, `TaskList`).
+- `cli.py` — the command-line front end. Reads/writes `tasks.json`.
+
+## Run it
+
+```bash
+python cli.py add "read module 1"
+python cli.py add "set up my editor"
+python cli.py list
+python cli.py done 0
+python cli.py list
+```
+
+Requires Python 3.10+ (it uses `list[Task]` style type hints). No third-party packages.
