### Step 4 Review your app release 

On the fourth step of distributing a new app release, you have all information together. You see again which build you will distribute, you see the release notes as well to how many testers you will distribute your app release.

#### Tutorial

{% hint style="info" %}
Are you annoyed to explain to your testers again and again how to install enterprise apps and how to accept unknown sources first?
{% endhint %}

If you have enabled the Tutorial switcher,  Updraft displays your testers a tutorial about **how to install Enterprise certified Apps while the download of the app is in progress.**

#### **One-Time-Link**

You can choose before sending your app release if the installation link your testers receive should be a one-time link. If it is a one-time link, your testers can only select the link once for the app installation. As soon as they will try to select the link a second time, an error message will appear and the app **cannot be downloaded again.**

### E-mail notification & app installation

If you click on **Send release button** all your testers and groups you added to your app release will get notified by e-mail. The will get an e-mail from Updraft with all configured information you did. They can just click on the installation button within the e-mail or scan the QR-Code to install your app.
