+# 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
+
+```BASH
+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
+
+```BASH
+git add repo
+```
+
