-1. Install a current JDK and Maven
-2. Run `mvn clean package`
-3. You can find the built executable in `target/app-image` and an installer in `target/installer`

-### Jar with dependencies
-To get a jar file with dependencies for your system, use `mvn clean compile assembly:single`.
+Starting with version 1.7, the recommended way to install the program
+is using the installer for your operating system from the [latest release](https://github.com/MaxiHuHe04/iTunes-Backup-Explorer/releases/latest).
 
-You can also build a fairly cross-platform jar file with dependencies for Windows, Linux and ARM macOS using the *most_platforms* profile: `mvn clean compile assembly:single -Pmost_platforms`
+### Windows
+Download and run the `_win_x64.msi` installer.
+By default, it installs the program just for your user
+and doesn't require administrator privileges.
+Then, simply double-click the shortcut on your desktop
+or use Windows search to launch it.
 
-## How to run directly using Maven
-Use `mvn exec:exec`
+### macOS
+Files ending with `_mac_arm64.dmg` can be used to install the program on Apple silicon processors (M1, M2, ...)
+while `_mac_x64.dmg` images support Intel-based Macs.
+
+You might have to go to `System Settings > Privacy & Security > Full Disk Access` and give the application 
+full disk access to prevent `Operation not permitted` errors when trying to export files.
+
+### Debian/Ubuntu
+Download the `_debian_x64.deb` file and install it using `sudo apt install ./path/to/package.deb`.
+The application is installed to `/opt/itunes-backup-explorer` and added to the desktop menu as an *archiving utility*.
 
 ## File Search
 In the "File Search" tab, you can search for files using case-insensitive SQLite LIKE syntax.
