REGISTER{my-app, {QmA, AddrA}}
```
The app name, `my-app` is used to encode a single shard in the form:
The app name, `my-app` contains the encoding of a single shard in string form:
```
<rs (utf8 encoded)> | <2-byte shard cluster index> | <2-byte shard index>
"rs/"| to_string(<2-byte shard cluster index>) | "/" | to_string(<2-byte shard index>)
```
The string conversion SHOULD remove leading zeros.
> *Note:* Since the [ns](https://github.com/libp2p/specs/blob/master/rendezvous/README.md#protobuf) field is of type string,
a more efficient byte encoding is not utilized.
Registering shard 2 in the Status shard cluster (with shard cluster index 16, see [WAKU2-RELAY-STATIC-SHARD-ALLOC](https://github.com/waku-org/specs/blob/waku-RFC/informational/relay-static-shard-alloc.md),
the register query would look like
```
REGISTER{0x727300100002, {QmA, AddrA}}
REGISTER{"rs/16/2", {QmA, AddrA}}
```
Participation in further shards is registered with further queries; one register query per shard.
(0x7273 is the encoding of `rs`.)
A discovery query for nodes that are part of this shard would look like
```
DISCOVER{ns: 0x727300100002}
DISCOVER{ns: "rs/16/2"}
```
