     Transformations can be associated with channels, working on data being passed between bindings and Items. See [profile documentation]({{base}}/configuration/items.html#profiles) for more detail.

+## `SCRIPT` Transformation
+
+The `SCRIPT` transformation is available from the framework and needs no additional installation.
+It allows transforming values using any of the available scripting languages in openHAB (JSR-223 or DSL).
+
+The script needs to be placed in the `$OPENHAB_CONF/transform` folder with an extension `.script` regardless of the actual script type.
+When referencing a transformation, the script type must be prepended to the filename (e.g. `dsl:stringlength` for the DSL version of `stringlength.script`).
+Please note that you cannot have transformations with the same name and different languages as the file-extension is always `script`.
+
+The input value is injected into the script context as a string variable `input`.
+The result needs to be returned from the script, it can have be `null` or value of type that properly implements `.toString()`.
+Additional parameters can be injected in the script by adding them to the script identifier in URL style (`js:scale?correctionFactor=1.1&divider=10` would also inject `correctionFactor` and `divider`).
+
+The examples show a simple transformation with the same functionality for some languages.
+It takes the length of the input string and e.g. returns `String has 5 characters`.
