 At the present, development is in very early stages, as this is an entirely crowd-sourced and volunteer-led project. We are focusing inititally on [Module 5](https://github.com/OpenScienceMOOC/Module-5-Open-Research-Software-and-Open-Source) to run as a pilot for testing and receiving feedback. After this, the protocol and content will be revised, and then applied accordingly to the development of the remaining modules.
