+
+Use the following steps based on our [getting-started](https://github.com/smart-data-lake/getting-started) guide to upload an SDLB configuration and runtime informations,  
+or select another tenant in the upper right corner.
+
+#### 1. Add global.uiBackend configuration
+Adapt _repo_ (repository name) and _env_ (environment name) to your needs and use [Secret Providers](https://smartdatalake.ch/docs/reference/hoconSecrets) to hide the _password_ of your UI user.
+
+    global {
+      
+      ...
+
+      uiBackend {
+        baseUrl = "${url}"
+        tenant = ${tenant}
+        repo = getting-started
+        env = dev
+        authMode {
+          type = AWSUserPwdAuthMode
+          region = eu-central-1
+          userPool = sdlb-ui
+          clientId = ${clientId}
+          useIdToken = true
+          user = "###ENV#user###"
+          password = "###ENV#pwd###"
+        }
+      }
+    }
+
+#### 2. Export SDLB configuration to the UI
+Use the _exportConfigSchemaStats.sh_  script from the [getting-started](https://github.com/smart-data-lake/getting-started) folder to export the SDLB configuration to the UI.  
+This will initialize and populate the _repository_ and _environment_ in the UI, so it is no longer empty.
+
+#### 3. Run SDLB Job
+Use the _startJob.sh_ script from the [getting-started](https://github.com/smart-data-lake/getting-started) folder to run an SDLB Job.  
+The SDLB Job will automatically pickup the global.uiBackend configuration and push its runtime information to the UI.
