I tried it out (see https://twitter.com/try_except_/status/1333499056769937408) and got great support in the Matrix/Riot chat (https://matrix.radicle.community). Definitely looking forward to distributed git changing the developer landscape :-)
The desktop client does not support Windows, and no plans at the moment :/
You should be able to get working with WSL2.
