 ## Prerequisites
 
-- Coder [`external-auth`](https://coder.com/docs/v2/latest/admin/external-auth) configured with Artifactory. This requires a [custom integration](https://jfrog.com/help/r/jfrog-installation-setup-documentation/enable-new-integrations) in Artifactory with **Callback URL** set to `https://<your-coder-url>/external-auth/jfrog/callback`.
+Coder [`external-auth`](https://coder.com/docs/v2/latest/admin/external-auth) configured with Artifactory. This requires a [custom integration](https://jfrog.com/help/r/jfrog-installation-setup-documentation/enable-new-integrations) in Artifactory with **Callback URL** set to `https://<your-coder-url>/external-auth/jfrog/callback`.
+
+To set this up,
+1 . Modify your `values.yaml` for JFrog Artifactory to add,
+
+```yaml
+artifactory:
+  enabled: true
+  frontend:
+    extraEnvironmentVariables:
+      - name: JF_FRONTEND_FEATURETOGGLER_ACCESSINTEGRATION
+        value: "true"
+  access:
+    accessConfig:
+      integrations-enabled: true
+      integration-templates:
+        - id: "1"
+          name: "CODER"
+          redirect-uri: "https://CODER_URL/external-auth/jfrog/callback"
+          scope: "applied-permissions/user"
+```
+
+> Note
+> Replace `CODER_URL` with your Coder deployment URL, e.g., <coder.example.com>
+
+2. Add a new [external authetication](https://coder.com/docs/v2/latest/admin/external-auth) to Coder by setting these env variables,
+
+```env
+# JFrog Artifactory External Auth
+CODER_EXTERNAL_AUTH_1_ID="jfrog"
+CODER_EXTERNAL_AUTH_1_TYPE="jfrog"
+CODER_EXTERNAL_AUTH_1_CLIENT_ID="YYYYYYYYYYYYYYY"
+CODER_EXTERNAL_AUTH_1_CLIENT_SECRET="XXXXXXXXXXXXXXXXXXX"
+CODER_EXTERNAL_AUTH_1_DISPLAY_NAME="JFrog Artifactory"
+CODER_EXTERNAL_AUTH_1_DISPLAY_ICON="/icon/jfrog.svg"
+CODER_EXTERNAL_AUTH_1_AUTH_URL="https://JFROG_URL/ui/authorization"
+CODER_EXTERNAL_AUTH_1_TOKEN_URL="https://JFROG_URL/access/api/v1/integrations/YYYYYYYYYYYYYYY/token"
+CODER_EXTERNAL_AUTH_1_SCOPES="applied-permissions/user"
+```
+
+> Note
+> Replace `JFROG_URL` with your JFrog Artifactory base URL, e.g., <artifactory.example.com>
