A mono repo is a git or any version control repo that has basically all of your code in the same repository. It doesn't necessarily mean that it's one program or one app that you are going to build or compile into. The benefit, right, is that whoever's working on the catalog, but they theoretically can just, stay focused on that little bit of code and not the entire system. Google uses basil and there's different tools that allow them that are kind of not just git, but something that can handle, you know, that scale of code.
