 ## Installation
 
+### Option 1: Pre-built Binary (Recommended)
+
+Download the latest release for your platform from [GitHub Releases](https://github.com/jamulix/NameToUnix/releases):
+
+```bash
+# Linux x86_64
+wget https://github.com/jamulix/NameToUnix/releases/latest/download/ntu-linux-x86_64.tar.gz
+tar xzf ntu-linux-x86_64.tar.gz

+tar xzf ntu-macos-arm64.tar.gz
+sudo mv ntu /usr/local/bin/
+```
+
+### Option 2: Build from Source

 Die ausführbare Datei wird unter `target/release/ntu` erstellt. Du solltest sie mit 'sudo cp target/release/ntu /usr/local/bin/' kopieren. Sie ist dann für alle User verfügbar. Denke daran, die Konfiguationsdatei (s. u.) ebenfalls zu kopieren. Sie kann für jeden User individuell angepasst werden, wenn sie im home-Verzeichnis des Users liegt.
 
 The executable file is created under `target/release/ntu`. You should copy it with 'sudo cp target/release/ntu /usr/local/bin/'. It is then available for all users. Remember to copy the configuration file (see below) as well. It can be customized for each user individually if it is located in the user's home directory.
