+VboxExtpackAutoinstall
+===================
+Simple script for automatic installation of VirtualBox Extension Pack.
+This is useful if your Linux Distribution doesn't come with Extension Pack installed by default.
+
+# Usage
+Just run the script:
+```bash
+./run.sh
+```
+It will automatically download correct extension pack version and handle the installation process.
+
+# VirtualBox / Extension Pack version upgrade
+If the extension pack stops working due to a version upgrade, just re-run the script:
+```bash
+./run.sh
+```
+It will automatically remove old version and fetch the new one.
