# Installing the Arist Comms app for existing Arist customers

1. Add the Arist Comms application to the Organization.
    
    * Go to Microsoft Teams admin center:
      https://admin.teams.microsoft.com/dashboard
      [https://admin.teams.microsoft.com/dashboard]
    
    * Under Teams apps, click on Manage apps, then search for "Arist"
      
      
      
      
    
    * Click on the "Arist Comms" application.
    
    * In the Arist Comms card, click on "Available to". On the right, change the
      dropdown option to either "Everyone" or "Specific users or groups".
      
      
      
      

 2. (Conditional): If your organization plans to white-label the Arist Comms
    app, this is the recommended time to do it. If you attempt to do the
    white-label after Step 3, it is possible that Microsoft will have already
    cached our original logo and won't immediately apply your customization.
    Here are the steps to white-label it.
    
    * Prepare Teams white-label customizations with official Microsoft
      specifications

 3. Configure App setup policies
    
    * Navigate to App setup policies
      [https://admin.teams.microsoft.com/policies/app-setup], then select the
      policy (default: Global).
      
      
      
      
      
      
    
    * Under the "Installed apps" section, click on "Add apps", then search for
      "Arist comms."
      
      
      
      
    
    * Click add.
    
    * Scroll to the bottom, then click Save.
    
    > ⚠️ Once saved we will have to wait for the changes to propagate, up to 1-2
    > days for propagating the App Setup Policy changes to all tenant members,
    > and another 1-2 days for the install itself to take place, depending on
    > the size of the tenant/the size of the group the App Setup Policy is
    > assigned to.
