+## How to use the "Do Nothing" app
+
+The **Do Nothing** dummy app needs to be launched before you can use it in the pref pane. For this, open a terminal and run the following commands:
+
+```bash
+appDir="/Library/PreferencePanes/SwiftDefaultApps.prefPane/Contents/Resources/ThisAppDoesNothing.app"
+
+if ! [[ -d "$appDir" ]]; then appDir="$HOME/$appDir"; fi
+
+# Remove quanrantine flag
+xattr -d com.apple.quarantine "$appDir"
+# Open the app
+open "$appDir"
+```
+
+After these 2 steps, the **Do Nothing** app should work when you pick it up.

     - The second is **"Other..."**, which obviously will allow you to select an application not in the list; with a caveat. In recent versions of macOS, the LaunchServices have become quite a bit smarter under the hood than they used to be. In practice, what this means is that although you can choose *any* application to handle anything, only valid associations will be preserved, as the LaunchServices is permanently looking for invalid or stale associations and removing them.
   - One final note: In the URI Schemes tab, you have the option of adding a custom URI Scheme (Removing them on demand is neither possible nor necessary, due to the same thing explained above). This options is provided for completeness' sake; you should virtually never need to use it, since Launch Services should be able to properly detect any valid URL Handlers. As a further cautionary note: If you add a custom URI Scheme when it is not needed, you may not be able to remove it except by uninstalling and reinstalling SwiftDefaultApps. Why? Because new schemes are by default associated to *"Do Nothing", which means Launch Services will always find a valid handler as long as SwiftDefaultApps is installed.
 
+### How to Find Out File UTI

+Run in your terminal the following command (replace my_song.mp3 by your file):
