You should develop a web presence that hosts both internal and external information about your project. The external portion of your page is important for visitors to understand what your project is about,  who are the team members, how to replicate the project, documentation, etc. The internal part can be used to organize your team and house material that you may not want to release publicly. A repository hosted on github or similar hosting service is sufficient and typical.

You can use the wiki to provide useful information and documentation about your project. At minimum, this should give a brief overview (abstract) of your project, discuss the organization of your repo, and provide other more high-level information that a visitor can use to better understand the project. You should post all of the materials that you have to generate for this class in the repo. This includes class presentations, reports, videos, etc.

Those that want to be more savvy can create another website. But the repo and wiki are sufficient for this class. You should send me a link that I can use to post on the class website. You can see examples from previous years at the same class website link.
