    You may want to make changes to your container, such as installing a different version of a software or forwarding a new port. You'll rebuild your container for your changes to take effect. 
 
-   **Forward a port statically:** As an example change, let's forward a port statically in the `.devcontainer/devcontainer.json` file. 
-
-   > **Note:** Remote-Containers and Codespaces also take care of dynamic port forwarding, but there may be instances in which we want to statically declare a forwarded port. 
+   **Open browser automatically:** As an example change, let's update the `portsAttributes` in the `.devcontainer/devcontainer.json` file to open a browser when our port is automatically forwarded.
    
    - Open the `.devcontainer/devcontainer.json` file.
-   - Uncomment the `forwardedPorts` attribute and adjust the port number as needed.
+   - Modify the `"onAutoForward"` attribute in your `portsAttributes` from `"notify"` to `"openBrowser"`.
    - Press <kbd>F1</kbd> and select the **Remote-Containers: Rebuild Container** or **Codespaces: Rebuild Container** command so the modifications are picked up.
