+#### `findpeer`
+
+> Retrieve the Peer Info of a reachable node in the network.
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.dht.findpeer(peerId, [callback])
+
+Where `peerId` is a IPFS/libp2p Id of type [PeerId](https://github.com/libp2p/js-peer-id).
+
+`callback` must follow `function (err, peerInfo) {}` signature, where `err` is an error if the operation was not successful. `peerInfo` is an object of type [PeerInfo](https://github.com/libp2p/js-peer-info)
+
+If no `callback` is passed, a promise is returned.
+
+Example:
+
+```JavaScript
+var id = PeerId.create()
+ipfs.dht.findPeer(id, function (err, peerInfo) {
+  // peerInfo will contain the multiaddrs of that peer
+})
+```
+
+#### `findprovs`
+
+> Retrieve the providers for content that is addressed by an hash.
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.dht.findprovs(hash, [callback])
+
+If no `callback` is passed, a promise is returned.
+
+Example:
+
+
+
+#### `get`
+
+> 
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.dht.get(key, [callback])
