+The **Cookidoo** {% term integration %} allows you to interact with your shopping lists of [Cookidoo the official Thermomix recipe platform](https://cookidoo.international/) within Home Assistant.

+
+## To-do lists
+
+This integration provides two non-sortable to-do lists:
+
+1. **Shopping list**
+   - Contains ingredients from recipes
+   - Items can only be `checked`
+   - Items cannot be `created`, `deleted`, or `renamed`
+
+2. **Additional purchases**
+   - Contains user-added items to purchase
+   - Items can be `created`, `deleted`, and `updated`
+   - Items do not have a `description` field
+
+For example, if you add a pasta recipe, ingredients like "500g pasta" and "2 tomatoes" will appear in your "Shopping list". You can check these items off as you shop, but you cannot modify the label.
+
+In contrast, in your "Additional purchases" list, you can freely add items like "Kitchen towels" or "Dish soap", and modify or remove them as needed.
+
+## Known Limitations
+
+{% important %}
+As Cookidoo cannot share shopping lists between accounts and everybody interacting with it uses the same credentials, make sure you protect your credentials accordingly. All users of your Home Assistant instance will have access to the same Cookidoo account.
+{% endimportant %}
+
+The Home Assistant to-do list interface allows both renaming items and changing their state. However, for the "Shopping list", only state changes (checking/unchecking items) are supported. Any attempts to rename items will not be saved.
+
+## Data updates
+
+The Cookidoo integration fetches data from the device every 90 seconds by default.
+
+## Remove integration
+
+This integration follows standard integration removal, no extra steps are required.
