# Settings - Transformations
<!-- START MAINUI SIDEBAR DOC - DO NOT REMOVE -->
**Transformations** convert a value or Item state into a different value or state.
Transformations can be used in many different instances including links between channels and Items, rules and scripts, and some Thing configurations.
The different available transformation methods must be individually installed via the **Transformations** tab of the add-on store.
To learn more about transformations, read the [transformation docs]({{base}}/configuration/transformations.html).
On this page you can manage all the transformations you have added to your system:
- **Add new Transformations**<br>
Add individual transformations using the <!--F7:blue plus_circle_fill --> plus button.
- **Configure Transformations**<br>
Click on any transformation in the list to see its configuration page.
- **Delete Transformations**<br>
Select multiple transformations using the top **Select** button and use the **Remove** button at the bottom or use the <span style="color: red">Remove Transformation</span> button on the individual transformation pages.
