+## How the releases are configured
+
+The releases occur in an account in the Google Cloud (See [here](https://console.cloud.google.com/cloud-build/builds?project=kubebuilder)) using Cloud Build.
+
+### To build the Kubebuilder CLI binaries:
+
+A trigger `build-kb-release` is configured to call [build/cloudbuild.yaml](build/cloudbuild.yaml).
+This trigger will be executed when any new tag be published. 
+The tags must be built from the release branch (Currently, `release-3`).
+
+Also, we have a trigger to generate snapshots builds from the master branch.
+This trigger will call [build/cloudbuild_snapshot.yaml](build/cloudbuild_snapshot.yaml)
+when any change needs to be performed on master.
+
+### To build the Kubebuilder-tools: (Artifacts required to use ENV TEST)
+
+Kubebuilder projects requires artifacts which are used to do test with ENV TEST (when we call `make test` target)
+These artifacts can be checked in the service page: https://storage.googleapis.com/kubebuilder-tools
+
+The build is made from the branch [tools-releases](https://github.com/kubernetes-sigs/kubebuilder/tree/tools-releases) and the trigger will call the `build/cloudbuild_tools.yaml` passing 
+as argument the architecture and the SO that should be used, e.g:

+
+For further information see the [README](https://github.com/kubernetes-sigs/kubebuilder/blob/tools-releases/README.md).
+
+### To build the `kube-rbac-proxy` images:
+
+These images are built from the project [brancz/kube-rbac-proxy](https://github.com/brancz/kube-rbac-proxy).
+The projects built with Kubebuilder creates a side container with `kube-rbac-proxy` to protect the Manager.
+
+These images are can be checked in the consolse, see [here](https://console.cloud.google.com/gcr/images/kubebuilder/GLOBAL/kube-rbac-proxy).
+
+The project `kube-rbac-proxy` is in the process to be donated to the k8s org. However, it is going on for a long time and then,
+we have no ETA for that to occur. When that occurs we can automate this process. But until there we need to generate these images
+by bumping the versions/tags released by `kube-rbac-proxy` on the branch 
+[kube-rbac-proxy-releases](https://github.com/kubernetes-sigs/kubebuilder/tree/kube-rbac-proxy-releases)
+then the `build/cloudbuild_kube-rbac-proxy.yaml` will generate the images.
+
+To check an example, see the pull request [#2578](https://github.com/kubernetes-sigs/kubebuilder/pull/2578).
+
+**Note**: we cannot use the images produced by the project `kube-rbac-proxy` because we need to ensure
+to Kubebuilder users that these images will be available.
+
+### To build the `gcr.io/kubebuilder/pr-verifier` images:
+
+These images are used to verify the PR title and description. They are built from [kubernetes-sigs/kubebuilder-release-tools](https://github.com/kubernetes-sigs/kubebuilder-release-tools/).
+In Kubebuilder, we have been using this project via the GitHub action [.github/workflows/verify.yml](.github/workflows/verify.yml)
+and not the image, see:
+
+```yaml
+  verify:
+    name: Verify PR contents
+    runs-on: ubuntu-latest
+    steps:
+    - name: Verifier action
+      id: verifier
+      uses: kubernetes-sigs/kubebuilder-release-tools@v0.1.1
+      with:
+        github_token: ${{ secrets.GITHUB_TOKEN }}
+```
+
+However, the image should still be built and maintained since other projects under the org might be using them.
