+This example demonstrates how the nf-schema plugin logging, when unrecognized parameters are given to a pipeline by a user, can be configured. In this case the validation will fail if there are any unrecognized parameters.
+See the [logging configuration](https://nextflow-io.github.io/nf-schema/latest/configuration/configuration/#logging) documentation for more information.
