+## Dependency Version Checks
+
+Roles that pin an upstream dependency's version carry a comment directly above the `_version`
+variable in `defaults/main.yaml`, pointing at the page where the current upstream version can be
+confirmed:
+
+```yaml
+# version-check: https://github.com/lightningnetwork/lnd/releases
+lnd_version: "0.20.2-beta"
+```
+
+Find every instance across the repo with:
+
+```sh
+grep -rn "# version-check:" --include="*.yaml" .
+```
