 Here's what you can do in the KCL script:
 
-+ Read resources from `option("resource_list")`. The `option("resource_list")` complies with the [KRM Functions Specification](https://kpt.dev/book/05-developing-functions/01-functions-specification). You can read the input resources from `option("resource_list")["items"]` and the `functionConfig` from `option("resource_list")["functionConfig"]`.
++ Read resources from `option("items")`. The `option("items")` complies with the [KRM Functions Specification](https://kpt.dev/book/05-developing-functions/01-functions-specification).
 + Return a KPM list for output resources.
 + Return an error using `assert {condition}, {error_message}`.
 + Read the environment variables. e.g. `option("PATH")` (Not yet implemented).
