-          ===================
-          This bundle contains:
-            Minecraft.Client   - compiled Linux binary
-            lib/               - all required shared libraries (GL, GLFW, png, zlib, X11 etc.)
-            run.sh             - launcher script
-
-          To run:
-          1. Download LCEWindows64.zip from the MinecraftConsoles nightly release:
-               https://github.com/smartcmd/MinecraftConsoles/releases/tag/nightly
-          2. Extract it and copy the "Common" folder into this directory
-             (so you have Common/ sitting next to run.sh)
-          3. Run:  ./run.sh [--width W] [--height H] [--fullscreen]
-          EOF
-
-          echo "Bundle ready: $BUNDLE"
