I need to create a Group Contract

All I know and read is that in order to have a successful group, there are certain strategies that work to help with interpersonal communication and decision-making & in the first meeting, I have some decisions about how the group will function.

Contracts allow a group to establish procedures and roles in order to move into the performing stage and you can get to the work more quickly. Please refer to Connery, B.A. & Voh, J.L. (1989). Group work and collaborative writing. Campus Writing Center, UC Davis

I would like an example of how a Group Contract should look and how a Group Contract should be formatted.

Thanks
