+
+1. Create the git tag for the release.
+  ```shell
+  git tag v1.10.7-syself.8
+  ```
+
+2. Export the release tag.
+  ```shell
+  export RELEASE_TAG=v1.10.7-syself.8
+  ```
+
+3. Run the release script.
+  ```shell
+  ./hack/release.sh
+  ```
+  This will create the manifests in the `out/` directory. And push the CAPI controller-image to http://ghcr.io/syself/cluster-api-prod/cluster-api-controller-amd64:v1.10.7-syself.8
+
+4. You can apply the generated `out/operator-configmaps.yaml` and `out/operator-provider-patches.yaml` to the management cluster.
+  ```shell
+  k apply -f ../cluster-api/out/operator-configmaps.yaml
+  k apply -f ../cluster-api/out/operator-provider-patches.yaml
+  ```
+
+5. Ensure that the configured `--source` flag in CSO and CSPH deployments is set as `oci`. If its not set as `oci`, edit the same in `addonprovider` for `cso` and `csph`.
+  ```shell
+  k edit addonproviders.operator.cluster.x-k8s.io -n mgt-system cso
+  k edit addonproviders.operator.cluster.x-k8s.io -n mgt-system csph
+  ```
+
+6. Ensure that the secret `cluster-stack` containing Github and OCI credentials exist and is same as that of testing-cluster. Otherwise modify it and copy the values from the secret present in testing cluster.
+  ```shell
+  kubectl-modify-secret -n mgt-system cluster-stack
+  ```
