Then wire it into Nostr by using nostr keys and signing.
GRASP is a new Satellite Service in Nostr for git repos. This can do all the heavy lifting that comes with git repos. Authentication is done by nostr signers, which means that you can push to repos based on your pubkey, using your nostr signer. Wonderful.
These Satellite Services are a good working model to support use cases that cannot be practically solved by relays, while making it easy to use in Nostr. We probably need more of these.
