+## Managing submodules
+
+This repository uses Git submodules for external dependencies. After cloning,
+run:
+
+```bash
+git submodule update --init --recursive
+```
+
+To pull submodule updates later use:
+
+```bash
+git submodule update --remote --merge
+```
+
+The helper script `add-submodules.sh` documents how each submodule is added and
+configured. Submodules are automatically updated by the
+[update-submodules.yml](.github/workflows/update-submodules.yml) workflow.
+
+## Testing
+
+Shell scripts under `local/bin` are validated with [Bats](https://github.com/bats-core/bats-core).
+Run `yarn test` to execute every test file. Bats is installed as a development
+dependency, so run `yarn install` first if needed.
