This is my own custom multi-loader template, and it is not open-source, it is source-available. I don't really mind if you use it, but I do not take responsibility and I will get very angry if you try to impersonate me due to default settings.
Run this to install the template:
npx github:Xyndra/CustomMultiloaderTemplate#template-helper
Note that this requires Node.js and Git to be installed on your system.
