Git Submodules
A git submodule is a feature in Git that lets you include a repository within another repository, like a mini-fridge in a kitchen. This is helpful for managing dependencies in your projects by referencing and tracking external repositories.
More Detail
It makes sense for instance to take the core libraries of IguanaX which are solid and mature and turn them into submodules which we could then use as new backend of a new server for this concept site.
