+## Submodule Management
+
+### Sync Existing Submodules
+
+After running `git pull` on an existing setup or setting up a new machine, restore submodules to their exact pinned commits:
+
+```bash
+git submodule update --init --recursive
+```
+
+### Update Submodules to Latest Upstream Releases
+
+To bump top-level submodules (like plugins) to their newest remote commits without breaking internal nested dependencies:
+
+```bash
+# Fetch latest commits for top-level submodules
+git submodule update --remote
+
+# Reset nested submodules to what top-level submodules expect
+git submodule update --init --recursive
+
+# Commit updated submodule pointers
+git add .
+git commit -m "Update submodules to latest versions"
+git push
+```
