 # sumologic-kubernetes-setup
 
 Setup image for the [Sumologic Kubernetes Collection](https://github.com/SumoLogic/sumologic-kubernetes-collection)
+
+The images are pushed to [public.ecr.aws/sumologic/kubernetes-setup](https://gallery.ecr.aws/sumologic/kubernetes-setup).
+
+The images are built for the following architectures:
+
+- `linux/amd64`
+- `linux/arm/v7`
+- `linux/arm64/v8`
+
+## Build
+
+To build image only for the build host's architecture:
+
+```shell
+make build
+```
+
+To build multi-platform image and push it to a registry:
+
+```shell
+make build-push-multiplatform REPO_URL=my-repo/setup BUILD_TAG=custom-tag
+```
