We just started using Slingshot on a project, partly because the way it works looks much more efficient to passing uploads through the server (which loads the server).
It hasn’t been touched for 6 years, which at first seems like a reason not to use it, but there appear to be people that are using it successfully. So I persevered, and got it to work.
The doco shows how to set up CORS permissions, but it does not work (perhaps outdated). I found a way to fix it, and would like to update the documentation.
I may also want to make other changes (like add some proper tests)
What I am saying is that I might be putting my hand up to maintain it. How would I do that?
