-The Anbox Cloud Dashboard offers a web GUI from where developers can create, manage, and even stream applications from their web browser.
-The dashboard is useful if you are new to Anbox Cloud or want a simple management interface.
+The Anbox Cloud Dashboard offers a web GUI that developers can use to create, manage and stream applications from their web browser. You can use the pre-installed dashboard almost immediately after deploying Anbox Cloud.
 
-[note type="information" status="Note"]The web dashboard is more oriented toward developers than end-users. However, it only uses available APIs and SDKs, and can be a good example to build your own web-based platform.[/note]
+## Prerequisites
+Before you can log into the dashboard, you must register your Ubuntu One account with the dashboard to authenticate.

-
-## Installation
-
-The dashboard comes pre-installed when you deploy [Anbox Cloud with the streaming stack](https://discourse.ubuntu.com/t/install-anbox-cloud/17744) or the [Anbox Cloud Appliance](https://discourse.ubuntu.com/t/install-appliance/22681). It sits behind a reverse proxy for performance and security reasons.
-
-## Usage
-
-To access the dashboard, go to `https://<your-machine-address>/`.
-
-The dashboard uses self-signed certificates. You might see a warning from your browser and have to accept the certificates manually.
-
-### Granting access
-
-Instead of implementing its own user management, the dashboard relies on OAuth for user authentication. The only OAuth provider supported right now is [Ubuntu One](https://login.ubuntu.com/). Future versions of Anbox Cloud will allow using other OAuth providers.
-
-If you haven't registered an Ubuntu One account yet, you can do that at https://login.ubuntu.com/.
-
-Before you can log into the dashboard, you must register your Ubuntu One account with the dashboard to grant it access.

 If you followed the instructions in the [Install the Anbox Cloud Appliance on a dedicated machine](https://discourse.ubuntu.com/t/install-appliance/22681) tutorial or in [How to install the Anbox Cloud Appliance](https://discourse.ubuntu.com/t/how-to-install-the-anbox-cloud-appliance/29702), you already registered your Ubuntu One account.
 
 To add more accounts, use the following command:
 
     anbox-cloud-appliance dashboard register <Ubuntu One email address>

 ### Creating applications
 
-Creating applications through the dashboard is done the same way as you would do with `amc` (see [How to create an application](https://discourse.ubuntu.com/t/create-an-application/24198)).
-Note that more advanced scenarios might not yet be possible via the dashboard and require going through `amc`.
+Before creating an application, you need the following:
+* An application manifest. A default application manifest is available based on the *Resource type* you choose for your application. You can customise various attributes of your application including the resource requirements for your application.
+* Optionally, an Android package with support for the target architecture.
 
-![Create an application|690x438](https://assets.ubuntu.com/v1/40dda4a6-manage_dashboard-add-application.png)
+To create an application using the dashboard, use the *Add application* button on the *Applications* list screen, enter the required and any optional details that you want to provide and select *Add application*. This screen also provides the option to customise your application manifest.
 
-### Streaming applications
+There may be more advanced scenarios while creating an application that cannot be performed using the dashboard and may require using the `amc` CLI. See [How to create an application](https://discourse.ubuntu.com/t/create-an-application/24198) for more information.
 
-The dashboard comes with in-browser streaming capabilities through WebRTC. It uses the [Streaming SDK](https://discourse.ubuntu.com/t/anbox-cloud-sdks/17844#streaming-sdk) under the hood.
+### Streaming applications
 
-You can select any application you previously created and start a streaming session.
+The dashboard has in-browser streaming capabilities through WebRTC. It uses the [Streaming SDK](https://discourse.ubuntu.com/t/anbox-cloud-sdks/17844#streaming-sdk).
 
-![Start a streaming session|690x352](https://assets.ubuntu.com/v1/6087fbd9-gs_dashboard_start_session.png)
+You can start a streaming session for any of the successfully created applications. An application is ready to be streamed when its *Status* is *Ready*. When you select the *Start a new session* icon for an application, you can specify the desired streaming attributes such as the screen resolution, frame rate, screen orientation before launching the session.
 
-For more information about the Streaming Stack, visit [About application streaming](https://discourse.ubuntu.com/t/streaming-android-applications/17769).
