+### 2. Create an App registration
+
+Use this script ![](../../Authentication/CreateDevAADApp.ps1) to create an App Registration.
+
+> You will need to create a client secret for the App Registration
+
+### 3. Update App Setting.json
+
+Update the `PublisherTenantId`, `ClientId`, `ClientSecret` and `Audience` in the ![Backend's appsettings.json](../../Backend/src/appsettings.json) with values from the App Registration.
+
+### 4. Update the workload.xml
+
+Update the following fields in ![WorkloadManifest.xml](../../Backend/src/Packages/manifest/WorkloadManifest.xml)
+
+```xml
+    <AADApp>
+        <AppId>00000000-0000-0000-0000-0f433e979e6c</AppId> <!-- Your application ID -->
+        <RedirectUri>http://localhost:60006/close</RedirectUri> <!-- Your application Redirect URI -->
+        <ResourceId>api://localdevinstance/TENANTID/Org.WorkloadSample/QJ</ResourceId> <!-- Your application Resource Id-->
+     </AADApp>
+```
+
+### 5. Build and run the Docker Image
 
 Run the following command to build and run the Docker image:
 
 ```sh
 docker compose up
 ```
 
-### 3. Authenticate to the DevGateway
+### 6. Authenticate to the DevGateway
 
 Once the container is up and running, follow the prompts in the terminal to authenticate to Fabric.
 
-### 4. Shutting things down
+### 7. Shutting things down
 
 Stop the running container and remove containers and networks by running the command below.
 
 ```bash
 docker compose down
 ```
+
 However, since the terminal is attached to the running container, you have to open a new terminal from the `DevGateway` folder to execute the command. You can also shutdown the container gracefully with `Ctrl + C`.
