If you need help developing a workflow for your submission to the challenge there are a few different webinars that you can watch: [DockStore](https://dockstore.org/) is a library of docker based workflows. For example, you can find the CWL and Docker files for [Kallisto](https://dockstore.org/containers/quay.io/collaboratory/dockstore-tool-kallisto) there. They've released a video tutorial covering Dockstore, CWL and docker development: ${youtube?videoId=%2DJuKsSQja3g} In addition, Seven Bridges has released webinar videos outlining how to build tools for the DREAM challenge on their platform: ${youtube?videoId=JdCsL%5FMSOrE} ${youtube?videoId=tDzzRq4YN9M} If you have any questions about preparing your submissions, please ask.
