+# Enhancing OpenShift Lightspeed with Custom Knowledge
+
+## Overview
+This guide explains how to extend the intelligence of OpenShift Lightspeed by integrating specialized knowledge for Argo CD, the Argo CD Operator, and the GitOps Operator. By configuring a custom Retrieval-Augmented Generation (RAG) database, you ensure the service provides precise, context-aware assistance for your GitOps queries.
+
+The OpenShift Lightspeed service leverages Large Language Models (LLMs) to provide intelligent, context-aware responses. To ensure the model has deep expertise in your specific environment, you can use the Bring Your Own (BYO) Knowledge tool to integrate a Retrieval-Augmented Generation (RAG) database.
+
+By connecting this database, you bridge the gap between general AI knowledge and specific technical documentation, ensuring more accurate troubleshooting and configuration advice.
+
+
+## Pre-packaged Knowledge for GitOps
+We have curated and optimized specialized knowledge sets for the following components:
+
+* ArgoCD
+* ArgoCD Operator
+* Red Hat OpenShift GitOps Operator
+* ArgoCD Agent
+
+This knowledge is packaged into a container [image](https://quay.io/rhn-support-alkumari/argocd-byok-image:v0.0.2) and can be configured in Lightspeed using the instructions below.
+
+## Prerequisites
+
+* You are logged in to the OpenShift Container Platform web console as a user account that has permission to create a cluster-scoped custom resource (CR) file, such as a user with the cluster-admin role.
+* You have an LLM provider available for use with the OpenShift Lightspeed Service.
+* You have installed and configured the [OpenShift Lightspeed Operator](https://docs.redhat.com/en/documentation/red_hat_openshift_lightspeed/1.0/html/configure/ols-configuring-openshift-lightspeed).
+
+Modify the OLSconfig CR to deploy the pre-packaged RAG database alongside the existing one:
+
+* In the OpenShift Container Platform web console, click Operators  >> Installed Operators.
+* Select All Projects in the Project dropdown at the top of the screen.
+* Click OpenShift Lightspeed Operator.
+* Click OLSConfig, then click the cluster configuration instance in the list.
+* Click the YAML tab.
+* Insert the spec.ols.rag yaml code:
+  Example OLSconfig CR file
+
+```bash
+apiVersion: ols.openshift.io/v1alpha1
+kind: OLSConfig
+metadata:
+  name: cluster
+spec:
+  ols:
+    rag:
+      - image: quay.io/rhn-support-alkumari/argocd-byok-image:v0.0.4
+```
+
+Note: Where image specifies the tag for the image that is present in the image registry so that the OpenShift Lightspeed Operator can access the custom content.
+* Click Save.
