+### Windows-Specific Issues
+
+**Interactive commands don't work or hang:**
+
+On Windows (especially Git Bash/MINGW), interactive Docker commands like `createsuperuser` may hang or fail to display prompts. Prefix the command with `winpty`:
+
+```bash
+winpty docker compose run --rm -it django python manage.py createsuperuser
+```
+
+**"No such container" errors:**
+
+If you see errors like `No such container: django` when trying to attach to a running container, use `docker compose run` instead:
+
+```bash
+docker compose run --rm -it django python manage.py <command>
+```
+
+This creates a new container instance rather than attaching to an existing one.
