+## A note about linting
+As we're not using a lockfile, our dependency versions are non-deterministic.
+
+This means we can install versions of eslint plugins with updated rules that cause the project to fail the lint check.
+
+Rather than [firefight](https://github.com/guardian/cdk/pull/564) this, we're simply not linting this project as:
+  - This project is never consumed by anyone
+  - This project doesn't run anywhere
+  - This project doesn't get updated too often
+  - Understanding the original lockfile issues is a time sink
