Right, I just removed Windows support from Kitten.
I swept the WSL 2 installation instructions to the end of the reference section (since they already exist and if someone does want to run it under WSL, I don’t want to make their life any harder than it already is) but if something doesn’t work under Windows/WSL 2, please don’t open an issue as Windows is not supported.
(Kitten is supported on Linux and macOS.)
