# Modify a Set > `n34 sets update` command **Usage:** ``` Modify an existing set Usage: n34 sets update [OPTIONS] Arguments: Name of the set to update Options: --set-relay Add relay to the set, either as URL or set name to extract its relays. [aliases: `--sr`] --repo Repository address in `naddr` format (`naddr1...`), NIP-05 format (`4rs.nl/n34` or `_@4rs.nl/n34`), or a set name like `kernel` --override Replace existing relays/repositories instead of adding to them ``` Use this command to update an existing set by its name. By default, providing relays via `--set-relay` or repositories via `--repo` will add them to the set's existing entries. To replace the current relays and repositories with the new values, use the `--override` flag. [passing repositories]: /commands.html#passing-repositories
