 ## Experimental Status
 
 Trin is a prototype Portal Network client. This implementation and the Portal Network specifications will continue to co-evolve.

+# Submodules
+
+This project uses [Git Submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules). If you
+just cloned the project, be sure to run:
+
+```console
+$ git submodule update --init
+```
+
+This page provides short overview of most common use cases.
+
+## Pulling in Upstream Changes from the Submodule Remote
+
+You want to do this when the remote version of submodule is updated. The simplest way to resolve
+this is to run:
+
+```console
+$ git submodule update --remote --rebase
+```
+
+> If you modified your local submodule, you might want to use different flags.
+
+If you run `git status`, you should see that submodule is updated. Commit and push the changes so
+others can use the same version.
+
+## Pulling Upstream Changes from the Project Remote
+
+If somebody else updated the submodule and you pulled the changes, you have to update your local
+clone as well. The message `"Submodules changed but not updated"` will show when running
+`git status`. To update local submodule, run:
+
+```console
+$ git submodule update --init
+```
