It contains the miminal kademlia setup based on the libp2p v.0.46.1 Kademlia example. It was later upgraded to the latest to date version - 0.49.0.
The project shows that start_providing method produces warnings in contrast with put_record or get_closest_peers: https://github.com/shamil-gadelshin/kad-example/blob/613564ee773d78dc47cfaf30547d5fbf9300fcce/src/minimal_kademlia.rs#L92
It was also tested with the latest master (90df86d9e77172123562f8247f436f3e6da891e0)
