 There are two ways to create a custom Runnable from a function:
 
-* `RunnableLambda`: Use this simple transformations where streaming is not required.

 To simplify this process, the Runnable interface provides two methods for creating configurable Runnables at runtime:
 
 * `configurable_fields`: This method allows you to configure specific **attributes** in a Runnable. For example, the `temperature` attribute of a chat model.
-* `configurable_alternatives`: This method enables you to specify **alternative** Runnables that can be run during run time. For example, you could specify a list of different chat models that can be used.
