+# Test paragraph
+
+You can build and publish to your personal Quay account installer-aro-wrapper image with as follow:
+```
+export ARO_IMAGE=quay.io/<your_account>/aroinstaller:<image_tag>
+make publish-image-aro
+```
+
+For the build step to succeed, we are now pulling images from quay.io/openshift-release-dev and they aren't publicly available. So we need to have extra auth for docker/pod
+man. Needed information can be found in `secrets/env` in ARO-RP.
+Note `secrets` repository isn't commited and is retrieved with `make secrets` command (details in ARO-RP documentation).
+The needed token is the one used for 'quay.io' in the `PULL_SECRET` environment variable.
+
+To be able to pull images for build and push your image afterward to your own account, `auth.json` should be something like
+```
+{
+  "auths": {
+    "arointsvc.azurecr.io": {
+      "auth": "<redacted_token>"
+    },
+      "quay.io/<your_account>": {
+        "auth": "<redacted_token>"
+    },
+      "quay.io/openshift-release-dev": {
+        "auth": "<redacted_token_from_ARO-rp>"
+    }
+  }
+}
+```
