+
+== Deploying the Lokistack
+You can use the {product-title} web console to install the LokiOperator.
+
+.Prerequisites
+
+* {product-title}: 4.10
+* {logging-title-uc}: 5.4
+
+To install the LokiOperator using the {product-title} web console:
+
+. Install the LokiOperator:
+
+.. In the {product-title} web console, click *Operators* -> *OperatorHub*.
+
+.. Choose  *LokiOperator* from the list of available Operators, and click *Install*.
+
+.. Under *Installation Mode*, select *All namespaces on the cluster*.
+
+.. Under *Installed Namespace*, select *openshift-operators-redhat*.
++
+You must specify the `openshift-operators-redhat` namespace. The `openshift-operators`
+namespace might contain Community Operators, which are untrusted and could publish
+a metric with the same name as an {product-title} metric, which would cause
+conflicts.
+
+.. Select *Enable operator recommended cluster monitoring on this namespace*.
++
+This option sets the `openshift.io/cluster-monitoring: "true"` label in the Namespace object.
+You must select this option to ensure that cluster monitoring
+scrapes the `openshift-operators-redhat` namespace.
+
+.. Select an *Approval Strategy*.
++
+* The *Automatic* strategy allows Operator Lifecycle Manager (OLM) to automatically update the Operator when a new version is available.
++
+* The *Manual* strategy requires a user with appropriate credentials to approve the Operator update.
+
+.. Click *Install*.
+
+.. Verify that you installed the LokiOperator. Visit the *Operators* → *Installed Operators* page and look for "LokiOperator."
+
+.. Ensure that *LokiOperator* is listed in all the projects whose *Status* is *Succeeded*.
