📥 How to Install

Windows

1. Download the latest NLCSetup.exe from the Releases page.
2. Run the installer and follow the prompts.
3. Open New Launcher from the Start Menu or desktop shortcut.

Linux

1. Download the latest Linux AppImage from the Releases page.
2. Open a terminal in the folder containing the file.
3. Make it executable:

chmod +x NewLauncher-*-x86_64.AppImage

4. Launch it:

./NewLauncher-*-x86_64.AppImage

If your desktop does not launch AppImages directly, you can still run it from the terminal with the command above.

Linux From Source

If you want to build the Linux AppImage yourself:

chmod +x linux/build_appimage.sh
./linux/build_appimage.sh

That script creates a portable Linux AppImage from the repository root.
