-=== Building Docker Images On ARM64
-
-If you run the Spring Cloud Kuberentes build on an ARM64 machine the docker images
-used for the integration tests will fail to run due to using the wrong architecture.
-This is because the Paketo build pack does not yet support ARM64.  To work around this you
-can run the build by passing `-Dspring-boot.build-image.builder=dashaun/builder:tiny` to Maven.
-
-For example:
-```
-./mvnw clean install -Dspring-boot.build-image.builder=dashaun/builder:tiny
-```
