# Settings - Transformations
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 Other tab of the add-on store.
To learn more about transformations, read the transformation docs.
