 Tags can be used to associate builds, you could use tags to represent the dev branch, an internal project or any team builds. If the same binary has been uploaded with multiple tags, you can specify a tagName to differentiate between them. This is usually not needed, as the SDK will identify the tag automatically.
 
+### Login Level
+
+Login levels can be configured to require login for certain actions (like downloading the update or checking for updates). They are set at [Emerge Tools Settings](https://www.emergetools.com/settings?tab=feature-configuration). You should match that level at the app level.

 The library is designed to skip update checks on the simulator. To test update functionality, run your app on a physical device.
 
+### Why I am not getting any update?
+
+There could be several reasons:
+- Update checks are disabled for both Simulators and Debug builds.
+- ETDistribution is intended to update from an already published version on ETDistribution. If the current build has not been uploaded to Emerge Tools, you won't get any update notification.
+
 ### How do I skip an update?
 
 When handling the response you can check the release version field to decide if it should be installed or not.
+
+### Can I use ETDistribution to get updates from the AppStore?
+
+No, since the binary signer is different (builds installed from the AppStore are signed by Apple), the update will fail.
+
+### Can I require login to get updates?
+
+Yes, there are 3 options for security:
+- No login required.
+- Login required only for downloading the update (can check for updates without login).
+- Login required for checking for updates.
+
+These options can be configured per platform at [Emerge Tools Settings](https://www.emergetools.com/settings?tab=feature-configuration).
