Radicle Repository Information:
------------------------------
Repository Name: $REPO_NAME
Repository ID (RID): $REPO_RID
Visibility: $VISIBILITY
User DID: $DID
Node ID (NID): $NID
Preferred Seed Nodes: $PREFERRED_SEEDS
Web View URL: $PUBLIC_EXPLORER
Default Branch: $DEFAULT_BRANCH
Current Branch: $CURRENT_BRANCH
Current Commit: $CURRENT_COMMIT
Repository Status: $REPO_STATUS
Seeding Peers: $SYNC_STATUS
------------------------------
Clone Command: rad clone $REPO_RID
Sync Command: rad sync $REPO_RID
Initialize Command (if not cloned): rad init --name $REPO_NAME --default-branch $DEFAULT_BRANCH --visibility $VISIBILITY
------------------------------
Notes:
- To clone, ensure Radicle is installed (see https://radicle.xyz).
- For private repositories, ensure you have the necessary cryptographic keys.
- Syncing requires at least one seeding peer to be online.
