+## Container based developer flow
+
+If you don't want to maintain a Node developer environment that fits this project you can use containerized commands instead of invoking yarn directly.
+
+```
+# format code and build javascript artifacts
+docker buildx bake pre-checkin
+
+# validate all code has correctly formatted and built
+docker buildx bake validate
+
+# run tests
+docker buildx bake test
+```
+
 Here are a few things you can do that will increase the likelihood of your pull request being accepted:
 
 - Make sure the `README.md` and any other relevant **documentation are kept up-to-date**.
