SSH into your game shell, and type this into the command line. This was taken from the link I put in my post above, and directly from @guu’s post a few replies up. I have just modified an additional mkdir to allow the files to be built somewhere.
If you don’t know 100% what you’re doing, do everything 1 line at a time, to make sure there are no errors etc. Some of the commands require a Y/N input. If you just paste everything in, it overrides these, and aborts the process.
You don’t need to type in the ## comments. They’re just comments.
