TD-StorageBay offers a variety of services, and this guide was created to help you identify what they are and how to get set up to use them properly.
Do note that TD-StorageBay is separated into a few parts, read the page on TD-StorageBay's structure and layout for information on that.
Since TD-StorageBay-Gen has its own wiki, this will only cover the features on the GitLab side of TD-StorageBay, as well as the IRC and mail servers, since both are shared.
GitLab, obviously, handles Git. To get started, read this guide.
