-.Procedure
-
-. To _manually_ install {pac} on a {product-title} cluster instead of the default installation with the {pipelines-title} Operator, run the following command:
-+
-[source,terminal]
-----
-$ VERSION=0.5.4
-$ oc apply -f https://raw.githubusercontent.com/openshift-pipelines/pipelines-as-code/release-$VERSION/release-$VERSION.yaml
-----
-+
-[NOTE]
-====
-For the latest stable version, check the link:https://github.com/openshift-pipelines/pipelines-as-code/releases[release page]. In addition, check the {pipelines-title} release notes to ensure that the {pac} version is compatible with the {pipelines-title} version.
-====
-+
-This command installs {pac} in the `pipelines-as-code` namespace and creates user roles and the route URL for the {pac} event listener.
-
-. Note the route URL for the {pac} controller created on the cluster:
-+
-[source,terminal]
-----
-$ echo https://$(oc get route -n pipelines-as-code el-pipelines-as-code-interceptor -o jsonpath='{.spec.host}')
-----
-+
-This URL will be needed later when you configure the Git repository hosting service provider.
-
-. (Optional) To allow non-administrative users to create repository custom resource definitions (CRDs) in their respective namespaces, create a `RoleBinding` object with the name `openshift-pipeline-as-code-clusterrole` in the namespace. For example, to allow a user to create a repository CRD in the `user-ci` namespace, run the following command:
-+
-[source,terminal]
-----
-$ oc adm policy add-role-to-user openshift-pipeline-as-code-clusterrole user -n user-ci
-----
-+
-Alternatively, apply the following YAML file using the `oc apply -f <RoleBinding.yaml>` command: 
-+
-[source,yaml]
-----
