I have prepared an installation guide in the server folder, those who do not know the installation can benefit from it.
I'm sorry I forgot to write how to open pack in the setup file,
Run the install.bat file in the PML folder as administrator and put the PackMakerLite.exe and PackMakerLite.json files into the Client/Pack folder. Then right click on root.idx file and press PML Unpack. After making the necessary adjustments, you can right-click the Root folder and press PML Pack to close the package.
