Submodules

Folders in this directory represent a snapshot of a GitHub repo. This method enables one to link dependencies to their project in a generic way. These days most modern languages have some way of distributing modules or components. C# has nuget. Rust has cargo. Python has pip. And it goes on.

Adding modules is easy

git submoudle add https://github.com/username/repo.git

That command links a dependency to your repo.

It's not official until it's added

git add repo
