# Building Workflows

Workflows are a set of 2 or more apps that are linked together by dependencies, or when the output of one app/ applet is the input to another app/applet. A workflow will allow for these apps to be ran after the dependencies are met without having to submit another job (unless there is an error).

We support the following options for building workflows: \* Native (GUI) \* WDL \* Nextflow

In order to kill a job/ workflow/ app/applet you will need to terminate the job/ analysis. Please use dx terminate or terminate in the Monitor tab in the UI.
