-## 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
-```
