+
+## Historical Data Download (Bulk Import)
+
+To download old history, use the `MANUAL_START_DATE` variable. This will fetch data in reverse chronological order from the current date (or `MANUAL_END_DATE`) back to the start date.
+
+```bash
+docker-compose run --rm -e MANUAL_START_DATE=YYYY-MM-DD garmin-fetch-data
+```
+
+**Options:**
+-   `MANUAL_END_DATE=YYYY-MM-DD`: Optional end date (defaults to today).
+-   `FETCH_SELECTION=...`: Limit what data is fetched (e.g., `activity,sleep`).
+
+*Note: Garmin archives intraday data older than 6 months, so very old detailed data (HR, sleep stages) might be missing unless manually refreshed in the Garmin Connect app.*
